Charlie Lee on Litecoin: “People like choices”

This past weekend there was a large Bitcoin conference held in Miami that attracted many of the major crypto developers, programmers, journalists and userbase for seminars and workshops.

Charlie Lee, creator of Litecoin, gave a very interesting presentation on the history of altcoins from 2010-2011.  He discusses some of motivations for creating an alt coin (such as Litecoin) as well as what unique features a few of them have that differentiates themselves from others.

During the Q/A at the end, someone mentions that Adam Back, the creator of HashCash, purportedly said that the ecosystem should just have one cryptocurrency, Bitcoin.  Otherwise new participants and laymen get confused and turned off when they learn there are hundreds of cryptocoins.

Charlie’s response was that he agreed with this position, that it would be helpful for the development, the marketing and the dispersion of the crypto meme, but that ultimately “people like choices.”  And that if it was not Litecoin that was the 2nd largest, some other token would be.  And thus Bitcoin users should be happy that Litecoin is the 2nd and not some other, like Dogecoin which has no actual development team.

[Note: the first few minutes of the video are missing. The slides are located here.]

Charlie also did an interview last summer with Newfination which covered Litecoin, Bitcoin and Coinbase:

Interview with Mark DeWeaver, co-founder of Quantrarian Capital Management

Earlier today I had the opportunity to interview a friend, Mark DeWeaver.  Mark is the author of Animal Spirits with Chinese Characteristics and wrote a very kind foreword for my own book.  He worked in China for 9 years and later co-founded Quantrarian Capital Management which is fully invested in the Iraqi Stock Market.

We discussed a number of topics including the “rebalancing” of China’s economic model, the Soviet tech industry during Gorbachev1 , technological innovations with regards to the Great Firewall (GFW) and spent the last 15 minutes discussing cryptocurrencies, smart property, trustless asset management and specifically an article written by Mr. Sheng from the PBOC.2

Can Robert Wenzel Defeat the Encryption Used by Cryptocurrencies?

 photo NizeLinkedin.png Short answer, no.1 Back to that in a moment.

I am not sure who is doing the vetting process for investor relations at Ripple or Silicon Valley Bank (SVB), but if you are running a crypto-related business be aware that not only is Robert Wenzel (aka Raymond Nize) — the proprietor behind EconomicPolicyJournal — dogmatically anti-cryptocurrency but also not who he says he is.

Why make a blog post about this in the first place?  You may consider this water cooler minutiae and frivolous scuttlebutt, however you are known for whom you associate with.  If you hang out with known con-artists — even if you agree with some of what they say, this reflects poorly on you.  Especially when their entire motivation is not to genuinely learn about your product (crypto), but to merely hype their own investment schemes (e.g., commodities specifically gold).

Sock puppet extraordinaire

Last week I received some trollish comments from “Paul Trombley” (paul.XXXXXX@yahoo.com) regarding a lengthy post on this site (an expose of Nize’s sockpuppets), “Paul” states:

Wow. Utterly fascinating. Wish we could find out where Raymond Nize, et al., grew up and went to school, where he has worked, whom he dated, etc.

In the meantime, I will have to be content with another viewing of Pacific Heights.

A quick google search find four sites that zero in on the possible identity of “Paul”:

Obviously even if I had IP addresses this would not be a smoking gun.  But what are the chances, that a sock puppet posting on the only Nize/Wenzel thread on my site also links to EPJ and discusses many of the same topics in the same tone as Nize/Wenzel does?

Why is this important again?

Because Nize/Wenzel has managed to convince some important cryptocurrency personalities and institutions that he is someone who he is not.  He managed to convince Joseph Salerno that he has 20 years of experience on Wall Street. Where did he work?  His current LinkedIn profile (screenshot 1 2) is completely empty in all but the previous 6 years.  Surely someone with the pedigree he says he has would dutifully link to it and his past associates.

Is this an ad hominem?

No, he is making claims about his past life that are untrue which have in turn built up his credibility as a financial guru.  He has then taken these ill-gotten reputational gains and is now providing investment advice to readers and listeners of his website (which is just one of many websites he has created over the past decade under about 10 different pseudonyms, see Part IV for more).

To top it off, he has a clear anti-cryptocurrency agenda that involves spreading misinformation and/or propaganda.  In nearly every post about Bitcoin or some other aspect of cryptocurrencies he drags it through mud while simultaneously showing his inability to full comprehend how cryptography works.  Hint: if cryptography worked the way he describes it, the entire global financial industry, the diplomatic corps, cloud services and all e-commerce (to name a few) would effectively be unable to securely transmit data.  Trace Mayer did an excellent job pointing this out in the EPJ comments yesterday (SS).  Thereupon Nize notes how in his visits to both Ripple and Silicon Valley Bank he left unconvinced of cryptocurrencies potential (SS).

Strawman made of hand-waving

It is certainly understandable to not be convinced of the merits of a particular asset class, that is not the issue.  Not understanding public-key cryptography and then building bi-weekly cryptostrawman to thwack at, is a problem.  While the math may indeed be confusing to beginners and experts alike, the crypto algorithms used by cryptoledgers like Bitcoin and Litecoin are solid.

In fact, there is an monetary incentive to try and break them and no hacker has thus far been able to.2 If Nize truly believed that this crypto did not work, he could take the alleged holes he claims exist and tap into and forge 12.2 million BTC namespaces/addresses (and 25.1 million LTC).  He needs to show us a broken blockchain to prove his claim, yet has not.  If the pseudonomyous features did not work, then he could name the Top 500 BTC holders, but has not.  Disagree?  Who owns the 268th largest BTC address, the one with 4,719?  If the crypto is bad, did you break into it already?

Perhaps he will come around at some point, but this still does not justify the fraudulent personality that visitors are unaware of (and whom have given goodwill towards).  The lesson for investors doing road shows and presentations: do you due diligence and vetting upfront.3

  1. There are theoretical ways to forge entries in the blockchain, such as a 51% attack, but the crypto in the actual generic wallet most people use is currently not known to be brute-force crackable. []
  2. Nize also has epistimological problems regarding apriori utility and value but that is besides the point. See: The value of cryptocurrencies as well as Economics of Bitcoin by Peter Surda []
  3. As an aside, his Google AdSense has generated, ironically, Bitcoin-related services like Gyft that are displayed on his site — here is a screenshot. []

Q&A with Meni Rosefeld of Colored Coins

I had an email exchange with Meni Rosefeld who is on the core dev team for Colored Coins.  Below are his answers to my questions (published with his permission):

Q: What advantages does CC provide to the current global asset management industry?

A: The greatest advantage is the removal of barriers of entry. Currently, new businesses wishing to raise capital use cumbersome and inefficient private deals; and those aspiring to be listed in order to allow for the market to valuate them with an efficient mechanism, can only do so with a great expenditure. With colored coins, anyone can easily raise funds in exchange for equity, removing barriers of entry, encouraging innovation and allowing society as a whole to better allocate its resources between ventures.

Q: One criticism of CC is that it still requires centralized servers to issue and track tokens.  If this is the case, would it not be easier to simply do all trade privately at the centralized exchange where it will be more scalable and private?

A: No centralized servers are needed for tracking – this is done in the decentralized network of the host currency (such as Bitcoin). There does need to be an entity issuing each particular colored coin – however, an entity raising funds for a generic purpose is not usually in the business of running an exchange. Without colored coins, they would have to resort to a large 3rd party exchange with all the usual problems of barrier of entry (for both issuers and exchanges) and vendor lock-in. With colored coins, they can outsource the tracking and exchange to the efficient decentralized network. The issuer is only involved when issuing or recalling the coins; investors can then trade the coins between themselves without involving any 3rd party, which has implications for privacy, efficiency, and the kind of advanced transactions one can do.

Q: How does CC able to differentiate itself from other endeavors such as Ripple and Open Transactions?

A: The distinctive feature of colored coins is that it’s integrated into a host blockchain such as Bitcoin. OT and Ripple work very differently from Bitcoin and thus have an adoption curve in both people’s ability to understand the system and the existing hardware, software and business infrastructure. With colored coins built on top of the established currency Bitcoin, it enjoys all of Bitcoin’s known advantages, and will be more easily adopted by users of Bitcoin (who are anyway the ever-growing target market).

Ethereum’s potential: a cursory look

If you haven’t done so yet, I highly recommend reading Vitalik Buterin’s overview of Ethereum published earlier today.  It is very lofty, seemingly feasible and I don’t detect much hyperbole.  He is clearly aware of the short-comings of all the different 1.0/2.0 projects and is pretty much trying to make this stand out by otherwise fulfilling Newton’s, “standing on the shoulders of giants.”  I’d be interested to see what other project leaders from 2.0 initiatives have to say.

A few technical concerns I haven’t really seen addressed but I’m sure are being discussed somewhere:

1) Botnets.  While ASICs do create potential long term centralization problems, Botnets will jump all over the ability to use CPUs again to mine.  How can this be prevented/mitigated?  Can it?  Is there a way for Ethereum the org to prevent miners from participating (if so, can it be abused?)?  [Note: I have discussed mining previously in the Litecoin category.]
2) Even though the money supply is mathematically known, I’m not entirely sure the linear money supply will necessarily have the zeroing effect apriori.  It could, and probably will but obviously this is aposteriori.  For perspective, the token supply in LTC and BTC are significantly higher the first decade than Ether is.
3) While Script is not Turing-complete this also prevents viruses from being created and wreaking havoc on the blockchain.  CLL sounds great on paper in terms of robustness and utility, but how do you fight HNWI hackers who want to cause mischief?

Two other points of interest regarding the business side of this project:

1) I do think that eventually someone, somewhere will create a distributed, encrypted dropbox for global use.  How that is incentivized, or rather, how individuals pay for the resources (bandwidth & space) obviously will be another matter altogether.  Bitcloud is one project that is trying to tackle that (through proof-of-bandwidth).  Perhaps, as part of what Mike Hearn described 2 years ago, users will eventually be able to use microtransactions (e.g., 0.01 BTC) to pay random WiFi hotspots to create adhoc mesh networks — distributed encrypted dropboxes could just as easily follow similar paths in terms of payment/compensation.  Shades of Snow Crash and The Diamond Age

2) Even though I am pretty pro-alt coin/chain/ledger/etc. I do think parts of the Humint project are probably not going to work as initially planned in their press releases this week.  Assuming that Cocacolacoin is not part of the Ethereum blockchain but rather uses its own independent blockchain, it’s hard to imagine how to incentivize network hashrate (which creates network security which prevents a 51% attack).  I’m not saying it won’t work apriori, but from a business model it is difficult to believe that Bob the Miner will want to exchange hashrate for Coca-cola swag.  Obviously stranger things have happened, like the recent “success” of meme-related Dogecoin (wow! so cool! much awesome!); I do think not using the term “coin” will be a better marketing strategy as it is too loaded at this point (I prefer token or ducat).  Other obvious uses within the Ethereum blockchain are Frequentfliercoins from Alice Airlines, could probably help prevent and mitigate the risks involved in travel hacking (FYI: United Airlines frequent flier miles were downgraded effective February 1, 2014 due to rampant inflation).

For example, I think Alice Airlines could utilize the “contract” system by using some amount of Ether (0.01), creating a “contract” which defines a set amount of Mileage (which itself will likely have some predefined expatriation dates).  Assuming this is in the future and flyers are using Ether wallets (oh the 19th century irony) and provide the airline with their wallet address, the user will be able to receive the Mileage amount in their wallet (more than likely it will be an embedded URL that sends you to a screen on Airline Alice with the actual amounts + Terms of Service).  This is what colored coins are, but Ethereum seems to be both more elegant as this is native built-in functionality and in terms of transfer speed (3-30 seconds is the stated goal versus 10 minutes for 1 BTC confirmation).  This is subject to change, but just one potential use of the platform.

It will also be interesting to see how Dark Wallet and Zero Coin projects will react to this announcement (Ethereum is currently stating it is not an anonymous solution though through the “contracts” system this can be obfuscated).

What are smart property and smart contracts?

I have received a number of calls and emails regarding the concept behind smart property and smart contracts which have been in the news this week.  While this topic will eventually fill volumes, if you have some time I recommend reading through these links, all written by Nick Szabo:

Speaking of which, I had a short email exchange with Mr. Szabo today (who to the chagrin of redditors, insists he is not Satoshi) and he is familiar with what is going on in the ecosystem (including projects like Mastercoin and Ethereum and people like Mike Hearn).  So if you have been following his academic output, it is pretty neat to see how his ideas (like “the god protocol“) are coming into fruition through the advent of cryptoledgers and cryptocurrencies.

I also highly recommend his piece: Shelling Out – The Origins of Money

12 Step Guide: Easiest and fastest way to start mining Scrypt-based tokens for Litecoin and Dogecoin

This past year I have received a lot of emails asking me about how to mine a cryptocurrency.  There are lots of good guides out there for setting up real mining rigs.  I used this consolidated guide last year but I recommend Cryptobadger for all current setups.

But if you really want to just test the waters with a machine you have laying around, I put together a very simple guide involving the least amount of technical prowess.

Step 1: Find, build or borrow a computer with a discrete video card made by either ATI (now AMD) or Nvidia.  Radeon cards perform the best usually by an entire order of magnitude.  Do not use a laptop because it will likely overheat and you may end up causing permanent damage to the machine (the only exception is a gaming laptop with fans/exhaust).

Step 2: Look at the Litecoin mining hardware comparison chart (even though it says Litecoin, you will end up with the same hashrate with Dogecoin or other Scrypt-based cryptocoins).  Make sure to see what parameters and settings your discrete card functions best at.

Step 3: Download the GUIMiner fork for Scrypt-based cryptocurrencies (Litecoin and Dogecoin are the two largest in this space).  Note: the original GUIMiner is designed for Bitcoin and will not work if you point it to a Scrypt-based pool.

Step 4: Look for a pool.  You will unlikely be able to “discover” one of the blocks solo-mining with your own computer at this point, thus virtually everyone connects to a pool (a group of other miners) in which you collectively are rewarded for your share of hashing.  For Dogecoin there are numerous pools, the one I’ve mentioned to my friends is Dogehouse.  For Litecoin there are also many to choose from.  The one I personally used in China was Coinotron.  Note: pay attention to pool fees.  Some of the fees can be relatively high, 5%.  This is likely due to maintenance costs to prevent DDOS attacks from taking down the pool.  Also PSA: if you plan to add a lot of hashrate I recommend joining a P2Pool to help decentralize mining.

Step 5: Sign up for a pool.  When you register at one of the pools, be sure to use a password that only you know for the front-end otherwise someone can log in and modify the remittance address to their own.  Once you have registered, you need to do two things:

1) Create a worker unit with a name like Alice.1 and give it a simple password like X.  It doesn’t matter if someone knows that unit name or password, in fact they could actually point their cards to that address and help you mine, but that is unlikely : )

2) Look at the Getting Started section of the pool website.  There you will find the information about stratum and pool connection info.  You need to insert this information into the appropriate sections on GUIMiner.

Step 6: Insert settings.  Again, find out what kind of video card your computer is using and look at the comparison chart (above) to find out what the best settings are for that card.  If you use a Radeon you can use GUIMiner’s drop-down option and it will automatically insert the setting values.  Otherwise you should just Google your video card and type “litecoin mining” or “dogecoin mining” (e.g., Radeon 7950 litecoin mining settings).  It is important to look at the specific brand as some are better than others.  CryptoBadger has a list of the best available to buy (or used).

Step 7: Test the settings.  Once all of the fields are filled in GUIMiner and you have registered at a pool, be sure to click Start on the stratum server.  Then move to the first tab and start the worker unit (GPU).  You will instantly know whether or not the stratum connection is invalid as there will be a warning statement at the bottom with “Not Connected” next to it.  If your card is actually working, you will audibly hear the fans blowing much faster and in the bottom right hand corner of GUIMiner you will see a hashrate (e.g., 600 kh/s).  If you do not see a hashrate, it is not mining.  If the Stratum connection is not working, you will not be credit with valid shares.  In the bottom left of GUIMiner it will say how many shares have been accepted as well as stales/invalid.  You can also check the mining pool interface/dashboard to see how each mining unit is doing.

Step 8: If the system is working, have it run for 5-10 minutes.  See if it crashes.  If it crashes, try to diagnose the reasons why.  Did you try to run other applications at the same time?  You will likely be able to utilize the system for any productive work as the GPU, CPU and system memory are preocuppied solving these “proof-of-work” math problems.  So do not use your main work system.  If your system crashes, you can ask the community websites (like LitecoinTalk) for help in troubleshooting the cause.  In my experience the three most common problems are 1) heat dissipation, 2) power supply & 3) intensity settings are too high.

1) Heat dissipation.  Most beginners do not realize that these GPUs will, at full load and intensity heat up to 70C+.  My own reached over 80C and operated there non-stop for months.  You need a way of dissipating this heat, either by cooling it down within a case (e.g., lots of fans or liquid cooling) or by building an open-air case (like a milk crate).  If you are using more than one GPU you will also likely need a PCI-e riser to allow air flow in your system — if the cards are next to one another they will likely crash due to heat issues.  Here is a how-to guide for installing risers.  If you want to try liquid cooling, you can follow how my friend Silas did it several years ago with Bitcoin.

2) Do not underestimate how much electricity your GPUs will suck up.  If tweaked properly for undervolting (using various software tools like MSI Afterburner and/or Trixx) you can reduce power consumption however if you’re a beginner you will likely need some spare wiggle room.  There are endless threads about the best setup but do not skimp on a good PSU.  A 750W from Corsair will power two Radeon 7950s without a hiccup.  A 600W will likely not (perhaps creating a dangerous environment).  Do not use any molex connectors or converters.  Use a real power supply that has enough native PCI-e connectors to the board.

3) Each card has its crashing point.  Push it too hard with too much heat or fail to give it enough electricity and it will crash.  Another issue, and this involves guess-and-check is to incrementally increase the workload and intensity on the GPU.  So if this is your first time, start at an intensity of 14 and build up from there.  If you start at 20 you will likely crash the system and not be able to know exactly why (e.g., did it get too hot?).  Pay attention to GPU temperature during this time, if it gets past 90C or increases from room-temperature very rapidly, it will likely crash due to heat-related issues.

Step 9: This short guide was to help you just test and start mining with whatever gear you had laying around.  If you want to throw some real money at this endeavor, I recommend looking through CryptoBadger’s site and some of the mining forums out there.  The Radeon 7950 is still probably the best value / hash / watt — but they are no longer made or sold in most countries (the exception is the HIS brand from Taiwan which can still be bought online sometimes).  You can find others on Ebay and Craigslist (or 58.com if you’re in China).

Step 10: Install a remote-login tool such as LogMeIn so you do not have to connect your system permanently to a monitor or keyboard (do not give anyone that log in info).  In most cases you can just leave the rig in a corner of a room near a window and check on it once or twice a day via the remote login.

Step 11: Calculate your hashrate and plug it into a Litecoin difficulty rating calculator.  Then look to see how much it costs in electricity to operate your rig.  Even if you are still generating dogecoin or litecoin each day, your electrical costs may create an unprofitable scenario (unless of course the tokens appreciate and/or the difficulty rating decreases).

Step 12: You have a binary decision making process.  Either turn off the rig (remember, this was supposed to be just a test run) or leave it on.  It can be a fun experiment to show your friends and family how distributed cryptoledgers actually work in terms of infrastructure, but you most likely do not want to bet the farm to build a server farm of these. [Don’t forget to get a Litecoin wallet or Dogecoin wallet to put those mined tokens in]

Coda:

I have written a few other articles on mining before (see here and here).  If you came here looking for Bitcoin mining, you are a couple years too late.  For independent hobbyists, ceteris parebus it is mathematically impossible to profit off of GPU mining for Bitcoin.  You can buy an ASIC but again, those are problematic in that there is a waiting list and you will likely not receive it in time to generate enough BTC to pay for the machine plus electrical costs.  If you want to experiment you can buy a USB ASIC for Bitcoin mining (such as a Bi•Fury) that simply plugs into a USB slot and goes to work (you do need to manage the software, I recommend Bitminter as it is the easiest to setup with.)

Another problem with the ASIC from an investment standpoint is that it is a depreciating capital good.  As the competition for hashrate continues (see this recent Bloomberg cover story) the network difficulty for Bitcoin increases dramatically by 10-30% at each reset (essentially every 2 weeks).  Thus even if you do mine enough BTC and/or it appreciates in value to the point where you pay off the initial capital costs, you will unlikely be able to resell the ASIC to anyone (because why would a buyer want to purchase a product that is no longer profitable in hashrate?).  Thus the only option you then have is to turn the ASIC box on to work on a different SHA256d proof-of-work cryptocurrency.  CoinMarketCap has a list of other altcoins, nearly all of the ones currently listed after #15 are SHA256d-based.

And if you want to try and use CGMiner or cudaMiner (for Nvidia cards) but are not sure how to, I recommend watching this video:

Building Smart Property Applications: Colored Coins and Mastercoin

[Note: below is my recent article published on CoinDesk.]

Cryptoledgers such as those utilized in cryptocurrencies like Bitcoin and Litecoin have the ability to be employed in other capacities.  They are not merely one-dimensional, one-trick ponies relegated to simple fiat-only exchanges.

For example, last week Kyle Torpey published an overview of several upcoming projects that utilize the Bitcoin blockchain to provide new features and financial instruments for users globally.  While it is uncertain that any or all will be successful in accomplishing their goals, these new innovations, like Namecoin before it, show that cryptoledgers can be integrated to provide rich functionality beyond the current token system.

For those unfamiliar with Namecoin, it currently acts as a decentralized DNS system that makes domain name censorship difficult, if not impossible.  It was created in 2010 as a modified version of Bitcoin and in 2011 the mining of Namecoins (after block 19200) was effectively merged with Bitcoin through a software update (e.g. pools had to use a new software release).  While Namecoin provides DNS functionality it can also be utilized to be used as a messaging system, torrent tracker and even as a notary (which other cryptocurrencies can do as well).

The next release of Bitcoin currently being developed, version 0.9, will include a number of changes.  In the words of lead developer Gavin Andresen it includes the ability for “developers [to] associate up to 80 bytes of arbitrary data with their transactions by adding an extra “immediately prune-able” zero-valued output.”

What this allows for is a little more space in the output section to provide users the ability to add some new data (such as a distributed contract) to be included via a hash.

Why is this important?

In 2012, Mike Hearn (a Bitcoin developer now on the board of Circle) gave a presentation in London in which he describes other financial instruments and practical business uses that a cryptoledger can provide through the use of “timelock” (technically referred to as nLockTime).  This makes it possible to build ‘smart property’ or contracts that in turn create a distributed digital verification system that bypasses the need for a central repository.   A couple examples Mike gives are the transfer of goods (such as a car) and the execution of a trust fund (through a will), both of which can be conducted without many additional intermediaries.  For example, if a car ignition system is reengineered to connect with a cryptoledger protocol, it could enable car owners to buy and sell vehicles remotely via trusted timestamping.  The execution of a will (e.g. disbursement of a trust fund) is also possible, albeit slightly more complicated in that someone would need to build a system that can scan obituaries for deaths and notify the blockchain of any changes.  In actuality the potential applications can be expanded to anything that involves rights verification such as stocks, titles to houses, digital media as well as the keys to houses and cars.  In fact, this past fall Mike gave another interview describing these potential applications in more detail.

Coloring within the lines

Another potential way to utilize a crypto blockchain to verify wares is through a process being developed called Colored Coins.  In a nutshell this endeavor allows users to “color” a token to represent a specific asset such as a car, home, boat, commodity, shares, bonds – virtually any type of asset (e.g., 0.5 BTC colored green to represent your home).  These tokens can then be exchanged, just like bitcoin tokens, by anyone anywhere.  This enables a decentralized, trustless form of asset management that uses a blockchain as both a ledger and transportation mechanism.

I spoke with Alex Mizrahi, who is leading the development of the Chroma Wallet used by the Colored Coin project.   According to him, “It is going to be very easy for the asset management industry as a whole to use Colored Coins.  For example, some of the first places we are going to have adoption will likely be real-estate and portfolio management.  In fact, for any type of asset management it’s going to be simple to issue his own color that represents his goods.  A portfolio manager can issue one color that represents a portfolio of stocks backed by the real holding and sell it globally.  If he is savvy and his products are good, his colors are going to have demand.  So transferring ownership is very easy, quick and safe — just like bitcoins.  In the real estate industry someone can issue their apartments using colored coins and have them float on the blockchain, or manage time-sharing based on color.”

I also spoke with Amos Meiri, head of dealing at eToro and also a member of the development team for the Colored Coin project.  I specifically asked him if it would be easier to simply conduct all trade privately at the centralized exchange where it will be more scalable and private.  In his view, “Centralized exchanges definitely have their advantages, but colored coins can be useful for following reasons.  First, users do not need to trust their bitcoins to a centralized exchange.  Companies cannot manipulate ownership records (to commit fraud, for example).  So basically, if somebody gives you an IOU, it isn’t a good idea to leave it with the person who issued it or to affiliated parties.  Another reason is that companies cannot control how its shares are being traded, thus it cannot block trade.   And lastly, there is no need to maintain servers or manage security due to its integration with the blockchain.”

While this is obviously easier said than done, as noted above, this idea of using cryptoledgers to manage smart property has inspired and motivated numerous other groups to work on similar efforts.  For example, Counterparty.co was recently launched this month.  Its mysterious, relatively anonymous development team has released similar open-source applications, documents, binaries and tools that allow users and entrepreneurs to build smart property functionality such as derivatives and dividends in a decentralized manner.  And three days ago, Jon Southurst discussed several other groups including Reality Keys which can utilize a crypto protocol to build a predictions market or a way to hedge against currency fluctuations.

Masters of the cryptoverse

This past week I spoke with Taariq Lewis, the founder and CEO of BitcoinBusiness, a Bitcoin Advisory firm and he is also the Smart Property and Business Development Lead of the Mastercoin Project.  Mastercoin is a crowdfunded, non-profit endeavor to create an open-source  distributed exchange protocol for Bitcoin.  The MC project has received more than $3 million in crowdfunding which has been used to pay for bounties, build tools and write documentation all of which is ultimately released open-source.

According to Taariq, “We are on the tip of the iceberg of the democratization of upper level finance and investment management.  One apt analogy is that the current system involves a highly siloed, highly centralized organization reminiscent to the music industry prior to P2P innovations.  We are now approaching the first wave of people being able to distribute financial products to each other on a peer-to-peer basis.  While this obviously has regulatory repercussions such as the SEC and CFTC oversight in the US, there is no ‘Wolf of Wall Street’ in crypto.  In fact, projects like Colored Coin, Counterparty and Mastercoin will create applications that will decentralize stock and bond exchanges allowing individuals and entrepreneurs to build dividend products and distribute the assets without middlemen.”

I also spoke with David Johnston, managing director of BitAngels and a board member at Mastercoin.  In his view, “Cryptocurrencies are more than a payment network, it is more than a new type currency or store of wealth.  It is a whole new platform and is a way for people to now make programmable money and that gives rise to smart contracts.  Now that this money is programmable I can put it into applications, I can create other digital tokens.  That’s what really gets me excited where anyone can build anything.”

The Mastercoin platform is still a work in progress and has gone through several iterations based on community feedback.  It also faces market competition from several others in this space such as Open-Transactions, Invictus (formerly BitShares) and potentially many others that learn of the potential business opportunities.   And as a consequence, it looks like a promising area for Christensen-style innovation.

Outside the dev world

For perspective I had an email exchange with Ryan Orr who is a professor at Stanford University (teaching Global Project Finance and Infrastructure Investment) and chairman at Zanbato.   He noted that, “with the recent wave of regulatory actions, I am personally feeling quite excited about how the “smart property” projects evolve in 2014.   It is starting to feel like smart property could be a much lower path of resistance for the bitcoin protocol as it establishes a “non-monetary” form of use that fulfills a valuable social purpose.  And thus it should not be viewed as a direct threat by regulators who are afraid of losing monopoly control of money. It is the “duality” of purpose of gold, where people can hold it under the auspices of non-monetary purposes, but also hold it for monetary purposes (eg. a hedge against inflation), that makes it so difficult for the governments to totally eliminate it as a form of money (even though the US government did try to do so in 20th Century).  If bitcoin can develop a similar duality, where the ‘smart property’ use makes it legitimate, and then people also can secretly hold it as an uncorrelated hedge against government dysfunction, then that could be pretty interesting.  In sum, it feels like the ‘smart property’ could become the ‘formal, legal, legitimate’ face to the project that can develop independent of how the regulators rule on the use of Bitcoin for monetary purposes.”

In addition, I also spoke with Ben Davenport, an angel investor and a member of the monetization team at Instagram.  While he does not necessarily endorse one specific project, in his view, “colored coin technology allows such centralized assets to be traded in a completely decentralized way.  Every single equity in the world has a central issuer — the company itself. But imagine the power of being able to make a trustless trade of stock for bitcoin with a stranger, at a distance, with no third party involved. With colored coins, I can construct a single atomic transaction which encodes such an exchange. That, to me, is the most important basic thing that colored coins can enable.”

The disruptive potential of smart property for the entire financial industry, not just fiat credit facilities, is enormous.  Charles Stross, the British Scifi author, recently criticized Bitcoin and the cryptocurrency endeavor, wishing that it die a quick death (in fire no less).  While his contentions were fallacious on a number of counts (especially regarding the environmental impact), ironically, he previously predicted seven years ago that near-future scifi authors are still probably missing something disruptively as large as the Internet 20 years ago or the smartphone was this past decade.

In other words, just as rewatching older scifi films that failed to foresee drones and self-driving automobiles seems dated, the portrayal of centrally managed financial products may one day be viewed as an anachronism of our not-so-quaint analog past.  Thus, Stross’ prediction of another unforeseen invention could very well be these smart property applications and digital financial instruments that are managed and transported by the very same cryptoledgers he dreamt of burning.

SilverFish, a Chinese Scrypt-based ASIC mining company, has vapor-like attributes

[Note: This is a slightly updated version of a post I made on reddit yesterday]

A new ASIC service/product just hit Sina Weibo (though it is not currently trending on Baidu or Weibo). They have announced that their ASIC mining systems for Scrypt will be turned on around June 1, 2014. They estimate that their product is faster than GPU mining in terms of hash / power consumption (~300 kh/s at 5W versus 160W for a Radeon 7850).

SF are accepting pre-sales for shares into this company (similar to ASICMiner business model). For 0.5 BTC you can buy 1 share of stock (until January 20th, today, when it goes up to 0.7 BTC).

Very little is known about the company, there are no personal names (the laoban could be Li Jun, 李钧) or business addresses attached to it. If you create an account and log into the system the share availability fluctuates widely but it is not clear why.  Yesterday it went from 690 to 802 in about 10 minutes and it is currently, as of this writing, at 1022.

According to his Weibo account, the founder of SilverFish is purportedly the same guy who founded a large Chinese BTC and LTC mining pool, F2Pool and another major website yibite.com.1  Both he and the operations are located in Beijing.

According to ifeng.com (a Chinese financial news site), the CEO of Yibite.com is 李钧 (Li Jun).  And according to a comment on reddit, this same mysterious CEO/COO also supposedly worked on Avalon / 阿瓦隆, the first successful ASIC mining machine for BTC.  Perhaps Guo Yifu (郭义夫) may know who if Li Jun is the mysterious CEO/COO since he also works on the Avalon project.

However, until they show a video of the actual chips with screenshots of the hashing results, do your due diligence.  For example, one other comment mentioned the boondoggle that was/is ScriptASIC.org. And another example, a couple weeks ago I wrote an in-depth article about similar credibility and claims issues with the Alpha Tech Scrypt ASIC.  I will update this post if I find anything new.

  1. A reddit comment says it is one of the biggest pools, it may be, at least as the hashrates could collectively be part of P2Pool. However if you look at the hashrate pool comparison charts LTC / BTC, F2Pool is not listed. Thus it is likely part of P2Pool. []

Smart Property in the news: Counterparty.co

A new project that utilizes a cryptoledger to create decentralized, distributed trustless asset management has been making the rounds: Counterparty.co

It’s legitimate in terms of the codebase and functionality.  Thus it will be very cool to see how other similar projects (Colored Coins, Mastercoin, etc.) germinate as well.  The disruptive potential of these innovations are enormous.

Cautious odds and ends for the weekend

  • A friend pointed out that The Guardian relinked to my story on Huobi and the CEOs personal bank account.
  • Last week Wired ran a story about BTCChina and the various regulations that are quickly rearranging the marketplace in China.  They quote one of my friends, Scott Freeman, who I interviewed for my book (disclosure: I do not own any equity in any exchange).
  • There is a big discussion now on reddit about Huobi removing the option to deposit fiat through the bank account of the CEO.  My only comment is I have not heard or seen anything about indictments/arrests/etc mentioned in subthreads there.  Thus the rumors on that thread about prosecution/lawsuits are most likely just FUD.
  • On a few other reddit and BTCTalk threads there are comments by people saying how Alibaba-owned sites still have cryptocurrency-related wares available and this somehow disproves the new rule passed down by Taobao.  Again, the new rule (Chinese) won’t go into effect until January 14th.  Furthermore (and this is my own speculation) even if all of the wares listings are not purged immediately, that does not mean you should rely on these ecommerce sites for your business model in the face of such rules.  At best it is a short-term solution, part of the cat-and-mouse game.
  • Tech In Asia has a good year-end summary of events in China regarding Bitcoin noting that “smaller sites such as Bitfash and IWannaBuy still accept Bitcoins, even for payments.”  TIA also does a pretty good job breaking Asian-related cryptocurrency news and hasn’t fallen into permabull mode.

My last comment regarding all of the news is one of caution.  Do your own due diligence before investing in a particular asset.  And remember, despite what a bull (or bear) might contend are blue skies and lollipops, there are many risks that could swing price levels around, quickly.  Caveat emptor.

Colored Coins and other ‘smart property’ extensions

I am not necessarily endorsing the use of this specific project but Colored Coins (Chrome Wallet) illustrates some of the cool potential features that a crypto protocol like that of Bitcoin (or Litecoin) can be used for.


Kyle Torpey has also written an excellent summary of the major known projects in this piece: Bitcoin 2.0 Explained: Colored Coins Vs Mastercoin Vs Open Transactions Vs Protoshares

New Taobao rule banning the buying and selling of crypto currencies

Taobao is one of the largest ecommerce platforms in China (it is part of the Alibaba group that also own Tmall).  I have written about it in the past (1 2 3 4) and recommend readers peruse a good piece from The Economist detailing the ecommerce empire that is Alibaba.  In addition, I do not think the analogy that “Taobao is the ebay of China” is entirely accurate — the WSJ has a detailed explanation for why this is a poor analogy (different business model involving ads).

Earlier this week Taobao published a new rule (Chinese) which goes into effect on January 14th.  The new rule bans the buying and selling of bitcoin, litecoin and any other crypto currencies (it actually includes a long list of altcoins).  It also bans the buying and selling of any crypto currency mining tutorial and guide as well as any hardware and software related to mining.

There are a couple threads on reddit that discuss the potential impact for the exchanges and what kind of wiggle room they may have (1 2).

Again, while the word “voucher” is not mentioned, this new policy probably will not help the recently created voucher workaround that BTCChina just implemented.  Thus the cat-and-mouse game continues.

Why are exchanges in China still allowed to operate?

I am asked this question frequently and currently I cannot give you a non-speculative answer.

My guesses are thusly:

1) That policy makers, despite knowing Bitcoin/Litecoin has the ability to bypass capital controls would still like to see if there are other potential “legitimate” uses for it.  Remember, this is a developing country that is trying to turn Shanghai into a real international financial center (pdf) through initiatives like the new Free Trade Zone.   So for example, maybe they have been briefed on the ‘smart property’ features of the crypto protocols (e.g.,  secure time-stampingproving ownership of tangible propertydecentralized DNS and new ways to sign contracts).  I doubt this is the case though.

Or:

2) Instead of being relegated to a paltry few options such as owning multiple apartments and/or sometimes sketchy wealth management products (WMPs) perhaps they would like to permit residents to diversify and try out new financial instruments.  And as happenstance cryptocurrencies are seen as a new alternative asset class.  While the PBOC officially stated that private ownership and public participation are okay for now, they do not seem to view cryptos as meeting their criteria as a “legitimate” asset class, withholding their stamp of approval.12

Remember, because of strict capital controls [pdf], PRC nationals cannot transfer more than $50,000 in foreign currency abroad each year, the domestic banking system has a very large captive consumer base from which to essentially extract rents from (e.g., no need to innovate as the market is essentially walled off from outside competition).  Again, these limitations are expected to change over the next decade, though officials and analysts have been saying that since at least 2008 when I first arrived in China.3

Or:

3) Perhaps I am an incorrect in my assessment of the PBOC which has been based on the stern comments from Sheng Songcheng, head official of investigation and statistics at the PBOC (see his recent essay “虚拟货币本质上不是货币” as well as my commentary here).  In contrast, my friend over at Aha Moments wrote this past week:

Of course, to a certain extent this merely reflects the general laissez-faire approach which characterizes the Chinese government’s approach to private wealth, an aspect of Chinese reality which understandably attracts little coverage in countries with more voracious governments. The reality on the ground is in fact almost unimaginable to younger inhabitants of, say, the United States or Western Europe. Not only is there is no capital gains tax in China, but C2C bank transfers are for the most part instantaneous and unlimited. I can send 50000 yuan to my buddy in Xinjiang and he will have it in seconds, all for a token transmission fee. You can also walk into any bank in China with the equivalent of one million euro in cash and deposit it with no questions asked. Simply put, the government’s policy is to leave people and their money alone. While they do endeavor to tax some income at the source, for the most part that’s about as far as they go.

Aha does have a valid point in terms of the C2C transfers, it was always easy for me to transmit this specific type of transaction nearly instantaneously (assuming you are using ebanking or an ATM — face-to-face service is still quite slow and tedious).  So perhaps there is a liberalizing strain within the PBOC policy making that has remained in the background regarding cryptocurrencies.  I don’t buy that though either.4

Or:

4) That policy makers are biding their time to see what, if any, international consensus is built around the regulation and management of exchanges.  There is no global standard yet, Singapore’s government is taking a hands off approach towards cryptocurrency right now whereas Denmark plans to regulate and oversee its use.  In the US, all fiat exchanges have shut down with the exception of Coinbase and that is because its founders had previous business relationships with Silicon Valley Bank (the partner bank).5 And even with this exception, Coinbase technically is not an exchange per se, but rather receives its coins through other sources like Bitstamp.net.

I think this is the most likely, as regulators can put a squeeze on the industry as a whole, forcing artificial consolidation and/or bankruptcies quickly.6 Then the PBOC and other peer organs will only have to worry about a handful or participants instead of 20+.  We already see the verification process being rolled out as customers at large exchanges such as BTCChina and OKCoin require national ID names and numbers in order to register and conduct transactions.  This will likely allow the PBOC and other departments to track capital flows to specific individuals.

A sell signal?

Yesterday the Financial Times published a report detailing the Chinese regulatory environment for cryptocurrencies.  It reconfirmed what I discussed a couple weeks ago, that fiat deposits at several exchanges, notably Huobi, are being transmitted through the CEOs personal account.

What struck me however was how several entrepreneurs went on record with FT, using their own identities to explain how they were bypassing regulations and/or finding loopholes.  Of course the inner libertarian in me cheers for a liberalized, self-organized world but a couple of their viewpoints seemed naive, short-sighted and wishful thinking.  And will likely end bad for them.  In fact, yesterday I was corresponding with Vijay Boyapati (who incidentally is the same person who convinced me of the long-term merits of cryptocurrencies and their protocols) and he asked me about the recent rise in price levels and if had to do with liquidity from China.

Here was my response:

I do think that the added liquidity (or at least the appearance of liquidity, who knows how deep it is on the Chinese exchanges) is helping buoy the price levels.  I don’t think it will last on the Chinese side, especially with articles like that from the FT.  PBOC staff read that newspaper, those comments are just going to make the officials want to close all the loopholes even more — at least that’s my guess.

24 hours later and the price for BTC token has dropped from ~5800 RMB to 4900 RMB and LTC token from 180 RMB to 145 RMB.  Who knows why, perhaps it will jump back up to those heights again tomorrow.  Self-reported volume on OKCoin and Huobi are still roughly the same as they have been the last few days.  Perhaps it is just the typical volatility.7

Yet the longer term issue still remains unresolved for several of these exchanges named in the FT piece: how to legally keep fiat liquidity flowing in both directions.  Are investors at exchanges prepared for the possibility of yet another December panic sale or hedged against a possible lower liquidity environment?  What about the personal liability issues that someone like Li Lin is now potentially facing in the event that a future audit takes place?  Perhaps now is the time to contact a risk management attorney to see if there other upsides (or downsides) to this nebulous guidance.8

That’s Illegal. from ChinaLawBlog and In Reversal, Cash Leaks Out of China from The Wall Street Journal []
  4. This current stance by the PBOC seems to have taken many by surprise.  For example, back in October 2013 Bobby Lee was interviewed on a local station called International Channel Shanghai (video).  At the 12:38 minute mark Bobby says: “I hope personally to see more government regulation on bitcoin to clarify what businesses can and cannot do with bitcoin, to clarify how individuals can and cannot buy and sell bitcoins.”  Again, I have not spoken with him, but I doubt what he had in mind was what the PBOC and other organs announced/enforced last month regarding banning 3rd party payment processors. []
  5. See Regulatory risks, challenges and opportunities of cryptocurrencies in China and elsewhere []
  6. This is all speculative but there may still be time for new market entrants to enter the industry and merge/acquire with competitors. []
  7. One new story that came out today is that Taobao has a new rule (Chinese) that will ban the buying and selling of crypto coins.  Thus it will purportedly impact vouchers such as those being offered by BTCChina. []
  8. I do not know if law firm Harris & Moure has any particular advice on these issues at this time, but Dan Harris publishes a popular site: China Law Blog that discusses many legal issues regarding the mainland. []

Should you buy an Alpha Technology ASIC for Litecoin mining?

alpha technology viper

Short answer, probably not unless you point it to another Scrypt-based token like dogecoin.  I’ll show you the math and hypothetical situations below, but quick story.

This past spring I helped build a couple simple Sapphire 7950-based mining rigs in Shanghai for a few friends.  At the time the new Vapor-X cards cost around $300 each and could be tweaked to run at around 600 kh/s (in line with these hardware expectations). [Note: This was also just before Cryptobadger, who has a great series of how-to guides, highly recommended if you’re interested in doing-it-yourself.]

Fast forward to early December, virtually all physical stores in any big city throughout China were sold out of the following Radeon models: 7950, 7970, R280, R280X.  My friends spent hours calling up and chatting to online shops from Taobao and Tmall to try and locate any supplier with product.  But all were backlogged for the next couple of weeks.  Why?  What had happened is that the price of litecoin tokens had popped on exchanges (namely BTCe and OKCoin) by a factor of 10x in less than 3 weeks ($2 to $20).  Yet the difficulty rating was still (temporarily) at around a mere 1,000 meaning that the return-on-investment for even a small rig composed of 7950s was relatively quick.  However that capital expenditure / token profit information traveled rather quickly, ending up on a variety of domestic evening newscasts.  And thus, there was a mad dash to get these GPUs.  As a consequence, I spent one early December weekend during this time combing the PC malls in Changning district trying to find any owner who could supply a couple dozen 7950s all in an effort to help some of my friends build a litecoin mining farm.  Yet each laoban explained (with a smile) that some large buyer had bought the remaining stock en masse — store by store.

We didn’t build that farm and in the short-run that may be okay.  While some miners simply look at the short-term seigniorage of flipping a few blocks, long-term mining operations probably will hold onto whatever tokens with a view that the tokens will appreciate by an order of magnitude.  Thus, while the collective hashrate for the capital expenditures for the 50 GPU cards my friends wanted to buy would have certainly been considered a profitable investment at the 1,000 difficulty rating, the longer term capital risks are substantially higher because the spread in crypto mining, like other commodity gathering, tends towards equilibrium (e.g., the cost of mining eventually equals the financial returns).  That is to say, the extra units of profitability (or unprofitablity) sends a signal to market participants to either continue one particular activity (like mining) or to shut down mining operations altogether.  You see this frequently in other capital intensive resource gathering spaces such as petroleum extraction as well as precious metals (e.g., if the revenue / barrel increases, other competitors will invest in new extraction techniques and/or open fields for development yet if the revenue / barrel decreases, competitors may shut off all production in a particular field).1

Again, crypto mining involves a scarce resource (block discovery in which the coin or token are part of) and in order to mine you need capital investment, in the form of a GPU.  Thus the same issues of supply, demand, price discovery and profitability now exist.2

ASIC mining

In 2011, Scrypt was adopted as the proof-of-work mechanism used by the Litecoin protocol.  It was purposefully chosen by Charlie Lee due the understanding that it was more resistant (not necessarily immune) to GPU and ASIC mining than the SHA256d proof-of-work used by the Bitcoin protocol.  And after two years into this altcoin experiment this assumption seems to have empirically played itself out as there have been no known litecoin ASICs.

Yet now that litecoin tokens are trading at ~$25+ each, the return-on-investment for physical design engineers (the people who actually design integrated circuits) to develop an ASIC has become within the realm of profitability for even something designed to be resistant such as litecoin.  That is to say, some group of investors believes that the capital costs of hiring a team to design, fab and sell an ASIC to litecoin miners is profitable (otherwise they wouldn’t do it).

At the end of last month, Alpha Technology in the UK announced that they were at the finishing stages of design for two products, a 5 MH/s and 25 MH/s ASIC for litecoin (remember, the ASIC you buy and use for bitcoin mining cannot be used for litecoin mining because it is designed specifically to work on one particular proof-of-work).  The 5 MH/s is expected to need 100W and the 25 MH/s version is targeted at 600W.

According to the announcement, the cost for the Viper 5 MH/s is £1350 ($2209) and the 25 MH/s is £5450 ($8918).  Not including electricity, taxes, shipping and pool fees, the top Viper at 25 MH/s works out to be around 2.8 khash per dollar.  This compares with a ~$300 for a new Sapphire Vapor-X 7950 @ 600 kh/s which is around 2 khash per dollar. [Note: most 7950s are no longer assembled as such and are now rebadged as R280, the big exceptions are HIS from Taiwan.  Cryptobadger has a run-down of the best cards available.]

Risks and variable factors

Despite looking legitimate through press releases and 3D renderings, the product might never come out.  Or when it does get released (probably late), the real numbers might be way off the estimates.

For example, last March a good friend of mine paid 50 BTC for 100 GHash/s ASIC from Butterfly Labs.  He received it more than 6 months later at the end of November.  If instead he had held that 50 BTC he would have been able to sell for $40,000 – 50,000 on many exchanges.  Instead, if you plug that 100 GH/s rate into a mining calculator, he will not even be able to mine 1 BTC for the next year at the current difficulty rating let alone ever be able to mine 50 BTC it cost to buy them.

So here is the likely scenario with Alpha Technology.  They will not ship for at least another two months.   Why?  The inner engineer in me asks: Has it passed verification process?3 Has it been taped out? What about maskmaking?  Those they do ship to are those who ordered first and there is a wait list (here’s a widely inaccurate waitlist).  Each minute you wait is another minute someone else will be ahead of you.

Now, assuming you were able to get the Viper 25 MH/s today, looking at the mining calculator to see how many litecoin tokens you would receive at the current difficulty (3366.7), the number is: 2408 LTC / year.4 Assuming the network hashrate does not collapse, that is the most optimal scenario you have this year.  And the highest price an LTC has gone for on an exchange so far was $50-$60 back in late November/ early December last year.  If this price level is ever reached again and the difficult rating never changed, then you would stand to make ~$125,000 which would make your $8,918 investment very fruitful!

But alas, this is not how it works.  Again, assuming the product is made and even shipped on time, the difficulty rating will continue to increase proportional to the additional hashrate.  So as more and more of these Viper’s (and/or other GPUs, FPGAs and ASICs) are added to the network, the higher the difficulty rating is adjusted to.

The next estimated difficulty rating is expected to be 3700 which knocks off 20 LTC more a month, dropping you down to around 2150 LTC / year.  But this is not the entire story.  You still need to factor in electricity costs, the transportation and shipping fees (unless you live next to the manufacturing and distribution center) as well as the pool fees.  Some pool fees, like at Coinotron which I used are 5% (it is this high in part because of the maintenance and admin costs needed to protect against DDOS attacks). 5

In all likelihood, unless you are the very first person on the list when the product ships, you would be better off either building an off-the-shelf GPU mining solution or buying LTC on an exchange and either hold for speculation and/or arbitrage.

Why?

Even if your electricity was free, you lived in the UK/India/China where they are manufactured and were the first person on the pre-order list, your first mover advantage would be quickly eroded by other Viper owners.  To give you an idea why, look at the current Litecoin Mining Pool hashrate.  If 200 other consumers bough 1 of each Viper, they would collectively add 6,000 MH/s which would place these ASICs alone as the 6th largest pool, increasing the hashrate proportionally (this is actually conservative because difficulty typically trails hashrate).

If litecoin difficulty doubled to 6,000 at current price levels ($27) and a 25 MH/s hashrate you would generate 125.7 LTC / month and earn enough monthly ($3,423) to pay for the machine in 3 months.

But instead, let’s assume for the moment that other market participants have access to similar mining calculators and how-to Cryptobadger guides.  And that over the next 6-9 months the difficulty rating jumps to 30,000 (9x the level today).  Impossible you say?  Last April when I got the initial litecoin rigs up and running, the difficulty rating was 300.  So in less than 9 months the rating has gone up 11x.

If it reaches 30,000 you would only generate 25.15 LTC / month which at ~$27 / token would generate $684 / month.  That means you would likely only generate enough litecoins (at current prices) to cover the costs for the Viper in the first year (ignoring all other pool fees, electricity costs, taxes, duties, etc.).

Sure the tokens could appreciate and increase in value, but as we continue to see, if price levels increase so too would competitor hashrate as others see a similar seigniorage opportunity.

That said, if these numbers are real, this Viper ASIC is only 40% better than GPUs in terms of hash/dollar. Of course this is just the first generation and other companies might be able to make more efficient chips. But this definitely is a positive sign that Scrypt hashing might be able to keep ASICs from totally dominating mining like it does with sha256d.

Money well spent?

One thing to constantly remind yourself is that like any investment, you should only spend money you can lose.  That is to say, as bullish as you may be on any particular asset class (including cryptocurrencies) there is always a statistical possibility that its liquid price could sink below whatever level you have bought at (e.g., underwater).  Perhaps even falling to zero.

If history is any guide (and perhaps it is not) looking back at the California Gold Rush (the 49ers) the firms who ended up financially in the black were merchants and service companies such as Samuel Brannan, Philip Armour, John Studebaker, Levi Strauss and Wells Fargo.6 Those who also made and sold mining equipment (picks, axes, shovels, sluices) had mixed results.  Yet the group of people who typically fared the worst financially were the miners themselves as they were nearly all exposed to various types of risks (upfront capital costs, land title lawsuits, inclement weather, sickness, etc.) and as a consequence, most ended up bankrupt.

Does this mean you should not purchasing crypto mining equipment?  No, but you are probably more exposed to risks with fewer potential upsides than downsides.  Your capital is tied up into a depreciating asset, a machine which unlike a GPU that can be resold, has a singular use that may or may not be delivered on time with unknown hashrate performance deltas.  Or you could be thinking, just like the first people who managed to get an Avalon batch last winter or a KnC miner when they ship new updates throughout the year (like the upcoming Neptune), perhaps you might be lucky enough to get a Viper that lives up to its paper reputation.7  But the odds are you won’t, especially if you are reading this and have not pre-ordered it.

One other option for HNWI is that you could invest in an IC design company such as Alchip which does the physical design for KnC.8 Or create your own engineering team to build ASIC machines for internal use only and sell public shares just like ASICMiner in Guangdong did last year.

Lastly, for entrepreneurs there are other areas to focus on beyond the token such as the financial instruments and applications discussed by Mike Hearn in 2012 that utilize the Bitcoin or Litecoin protocol (e.g.,  secure time-stampingproving ownership of tangible propertydecentralized DNS and new ways to sign contracts).9

Exhibit A:

Below is a very rudimentary table that utilizes this Litecoin difficulty calculator.10  The calculator is nowhere near advanced as the dynamic dashboard over at Genesis Block (which is BTC only).  In fact, this chart below does not include in its calculations the long tail of the difficulty curve.  It is an end-to-end snapshot (what it is today versus what it will be 6 months from now).  But that is unneeded as this shows you that in every instance, building GPU-based systems instead of buying the ASIC is probably more profitable in the first 6 months.  In some cases, merely buying LTC and holding is actually more profitable.

I should point out that for this activity I negated electrical costs which obviously are non-negligible especially for a large GPU farm.  Obviously an ASIC will come out per watt more efficient, so feel free to factor in whatever electrical costs you may pay on a monthly basis in your region.  I also assumed the consumer would be able to buy 32 new or used Vapor-X 7950s for $200 each and then simply build a barebone system using milkcrates as per Cryptobadger (Friendly reminder: anything that is not the GPU is not generating tokens and is therefore a money sink — you do not need fancy cases or i7 CPUs).  It is probably very difficult to locate 32 of these GPUs, let alone 42 for Scenario 4.  But you could likely find batches of used versions on eBay, Craigslist and other etailers.  They do not even need to be the Sapphire brand; see this chart for more comparisons.

The biggest difficulties for a massive GPU farm like that however will be logistics, cooling and storage.  You would need to have access to reliable power and internet sources.  You would also need to keep an eye on each of the GPUs throughout the day to make sure they are performing up to snuff (I actually used LogMeIn but I think Cryptobadger’s method is much more efficient).

Still, I would speculate that in all likelihood, the Viper is unlikely to be delivered to your door within the next 90 days.  If that is the case your two profitable options (based on this chart) are to buy and hold LTC and/or build a rig or two (depending on if you can get them used and what your electrical costs are).

One last note, I do not predict that LTC price levels will reach the numbers listed in this chart this year (if ever).  These are for illustrative purposes only.  In contrast, if price levels do continue to increase I would expect the difficulty rating to increase in a corresponding manner and that the lopsided disconnect in the last column would never germinate.  Baseline difficulty is 3300 and starting LTC price is $27.

Cryptocurrency Cat-and-Mouse games in China

btcc voucherSeveral updates to this ongoing cryptocurrency story in China and elsewhere (each subheading below is a slightly different topic).

Yesterday Bill Bishop linked to a story posted at Sina, “虚拟货币本质上不是货币” written by Sheng Songcheng.  Mr. Sheng is the head official of investigation and statistics at the PBOC (the central bank).

Bishop’s quick comment of the article was that, “No reason the belie[f] there will be any positive news from PRC regulators about bitcoin, or that somehow the recent crackdown was good, as some of the bitcoin bulls have been trying to spin.”

Too long; didn’t read

In addition to Bishop’s nutshell, another tl;dr comment that I would add is this, because Mr. Sheng works for the PBOC, his essay pretty much encapsulates what that important organ of the government thinks. Based on his essay, they do not recognize Bitcoin’s legality (although there is no clear indicator that they see a difference between protocol and token) and according to his own words, without government oversight or backing by any country, the token itself has no value.  Mr. Sheng uses the example of the recent 60% price drop of the bitcoin token on BTCChina last month as proof that without government approval, it has little value (a correlation-causation fallacy).  Furthermore, he thinks that if there is a developing country (such as China) that does begin using it, the deflationary aspect (the fixed ‘money’ / token supply) would actually present an obstacle and hinder the country’s economy to grow.  In fact, he says that Bitcoin and other cryptocurrencies will never become a country’s major currency and as a consequence, will not be a “real” currency.  And that it could only become so in the “utopian view of technocrats and libertarians” (技术至上主义和绝对自由主义者的乌托邦).  Yes, he uses the Chinese word for idyllic libertarian  (绝对自由主义者).

From a technical viewpoint, he states all cryptocurrencies do not have a unique origin, nor are its token generation, exchange and storage methods particularly special.  Any currency that has Bitcoin’s features could replace it such as Litecoin, which the public has become familiar with.  And continuing, he states that Bitcoin does not have any physical attributes found in gold and silver nor exclusivity enforced by the law so it will be really easy to replace.  Therefore it cannot replace the role of general currency which is the medium of trading. Thus his overall attitude (and that of the PBOC) is that the central government does not recognize any specific values of the token; that it is illegal to use (though he does not specifically say who or what timeframe) and it doesn’t justify its own existence.

Again, while we can argue over the epistemological, economic and technical problems with this essay (e.g., why do economies grow, deflation versus inflation [pdf], the economics of Bitcoin [pdf], what utility cryptocurrencies have, how the protocol works, etc.) all of which have been discussed elsewhere, as Bishop noted above, this essay is hardly a positive sign for the crytpocurrency segment in China.  Thus, while speculative, after reading the article the impression readers are left with is that the PBOC will crack down on cryptocurrencies on the mainland for the foreseeable future.

Cat-and-mouse

There have been discussions over the past weeks as to how mainland exchanges could bypass the current hurdles.  One idea was to create yet another type of virtual token that could then be exchanged on exchanges.

Over the past couple of hours on reddit, users have posted a new method that BTCChina is using to get around the current depository predicament the mainland industry is currently in (e.g., all payment processors are barred from providing fiat liquidity to crypto exchanges).  However, the small stop-gap solution is for BTCChina customers internally (this is not the same thing as the online vouchers like BTCe has).  BTCC code is to allow one customer with CNY on the site to sell the CNY to another customer.  The medium is the BTCC code which is in two parts: one is for the customer the other is for the site.

Imaginary Capital Markets has a few more details and screenshots, but let me just emphasize once more that this is not a complete workaround (yet) but just a way for BTCC users to exchange CNY with one another.  My speculation: if the CEO role as sole depositor is still active, perhaps this could be a way for him/her to distribute funds to friends & family who can then exchange the fund to the wider customer base.  If this is the case, perhaps other exchanges will follow suit (assuming that the CEO can still deposit funds into the exchange through their personal account, see the explanation here for more).

[Update: Taobao has a new rule (Chinese) that will ban the buying and selling of crypto coins.  Thus it will purportedly impact vouchers such as those being offered by BTCChina]

Also regarding the CEO bank accounts I discussed the past two weeks, Eric Meng, an American attorney friend of mine currently in China explained to me that the use of personal bank accounts to do business is a huge red flag in general.   It does not mean that anything is being done illegally, but it’s something that investigators watch out for.1

Bots again

Regarding the purported fudged numbers on Chinese exchanges (discussed here), another friend (in Europe) recently wrote to me explaining that someone could easily write a bot and test the liquidity to see whether it is real or not.  It could be that some exchanges on the global stage act as a market maker (similar to the NYSE which employs “specialists” [pdf explanation] who always make sure that there is a reasonable bid and ask available and who take short term positions in order to provide liquidity).

This same friend who has both mined and then built proprietary HFT arb software on BTCe is reasonably sure that BTCe runs their own arbitrage bots with zero fees but sometimes turns them off (or they have certain limits, he is not sure).  Again, arbitrage is not bad per se and basically makes sure that you can execute your orders at a ‘fair price’ all time.  Of course it would be better if the exchanges are more forthcoming about what they do behind the scenes but as long as there are no regulations they can do whatever they want and earn some extra money.  Yet again, no one is forced to use a particular exchange so people can easily vote with their feet or open their own (transparent) exchange.

Notes in the margin

One last comment I received is from Mark DeWeaver (author of Animal Spirits with Chinese Characteristics and GWON’s Foreword) is that,

It occurred to me that the argument about bitcoin having a big “carbon footprint” is really poorly thought out.  Is the footprint really bigger than that of paper currency, which has to be transported from countless businesses to bank’s safe deposit boxes at the end of each day.  And think of all the gas people must burn on trips to ATM’s!

This is in response to my explanation of Charles Stross’ contention that cryptocurrencies are more of a burden on the environment than fiat currencies are (they are not).  Mark’s comments are empirically valid because these up-armored vehicles (typically Ford 550 chassis or similar classes from competitors) are frequently used to move fiat currencies to and from distribution centers to branch banks and ATMs.  For example, The Armored Group currently lists many used armor transportation cars for sale.  And a quick search on Fuelly gives you an idea of how much fuel the average F550 consumes in the city (~9 mpg).  This also ignores the supply chain needed to build the vehicles in the first place which is an entire logistical segment that cryptocurrencies do not need.  Nor does it include the carbon consumption of the driver and guards ferried around in the vehicles (e.g., eating, sleeping, shelter, etc.).  One can only imagine the sheer number of vehicles in developing countries where digital fiat are not nearly as common and thus paper/metal is transported more frequently.

Again, this is not to say that cryptocurrencies are mana from heaven, that they won’t be replaced or will somehow axiomatically usher in a world of milk and honey.  But these specific claims by detractors need to be backed up with real numbers as they are positive claims (e.g., burden of proof).  If you do think that the Bitcoin transaction network (the most computationally powerful, public distributed system currently)2 consumes more carbon than all ~200 fiat currencies right now, you need to prove that.  And from my quick research I detailed in my article, that does not seem to be the case (today).

Also, for other occasional commentary on crypto in China I recommend visiting my friend’s site, Aha Moments (specifically this recent post).  Drop him a note and tell him to update more.

How to detect if a cryptocurrency exchange is fudging numbers

Huobi versus incumbents

Crypto volumes in China

This picture has been making the rounds.  The top section is the volume of LTC at OKCoin.  The middle of BTC volume at BTCChina and the bottom is the BTC volume at Huobi.  The yellow line is when the PBOC stepped in and told 3rd party payment processors / intermediaries they could no longer transfer RMB into crypto exchanges.

In the last post I mentioned that there are speculative reports that exchanges in China (and probably globally) are fudging their volume numbers (e.g., why the sudden dramatic drop-off at certain sites relative to others).

Why is this done?  Before answering that I should point out that it is quite simple to create a server-side app that dynamically reports a volume number during specific periods of the day (e.g., higher during the work day to mimic traditional stock exchange peaks and troughs).  Exchanges currently have an incentive to fudge these numbers in an effort to attract eyeballs by claiming they have the biggest volume.  This then becomes a self-fulfilling prophecy as market participants (e.g., speculators, day traders, etc.) discover this volume number through a news source and then setup accounts to begin trading on the exchange.

How can you tell whether or not this is the case in China or elsewhere?   Merely looking at blockchain.info would be pointless because the transactions at exchanges are internal and do not affect the blockchain until there is a deposit or withdrawal.  And after all, lots of investors like day traders never actually withdraw their bitcoins each and every day due to transaction fees.  Thus the only verifiable way is to actually go inside an exchange and look at their accounting / exchange database to see the true turnover.

How to fake (some) numbers

Because exchanges merely self-report whatever they want to, ultimately this kind of fakery is easy to spot if you publicly expose your market depth.

Another way is if you, the exchange operator, run your own bots which arbitrage to make extra profit yet your bots do not pay any fees.  Whether that is actually fake is arguable (see below), however since the trades are actually conducted this kind of activity is typically not practiced in many “real” securities exchanges (e.g., akin to NASDAQ operating the exchange and yet maintaining an internal trading desk whereupon it does not have to pay fees).

And another way is to simply mirror other exchanges and if you are mirroring, you may be fudging the numbers to disguise it, or not. You might execute the mirrored trades or just have them for show.  In fact, you do not copy all the orders exactly, you randomize the quantities and prices slightly.  The trick is to randomize the numbers, but keep your risk low by minimizing arbitrage opportunities (this can all be done via an HFT system).

So again, sites like BTC123.com aggregate Chinese volume numbers and assume that the self-reported numbers are valid.  Maybe they are, but there is no real transparency currently.  And I’m not sure how you can add transparency either.  And more seriously, how can you (the exchange) going forward publish accurate information and get the same audience that has been misinformed in the past to believe you once again?

It should also be noted, it is not always clear what is or is ethical / fake with this speculation.  As suggested above with the NASDAQ example, the lines between the trading exchange and the banking institutions that utilize it may be blurry (e.g., conflict of fiduciary responsibilities in the event you have duties at both).1.

Blatantly lying about your volume is obviously fraud.  But is trading in your own exchange (with bots or otherwise) wrong?  Is mirroring (as long as you are willing to execute the mirrored trades) wrong?  It is not clear whether that is wrong / fake, perhaps at some point a guideline of best-practices will become adopted industry wide that clarifies this.

At the end of the day, what counts is whether or not I can get a fill at or close to market price.  Thus, as a trader, I care if you just make up the ticker numbers.  But I may not care about mirrored trades, as long as I can still trade against them.  One last point: using bots and/or mirroring trades enough to have large volume is expensive and risky.  It takes millions of dollars to copy the same volume as the major exchanges and increases as the price of tokens increases.  And in all likelihood, many investors only have accounts with one exchange.  Otherwise the arb opportunities could not be so relatively frequent as they have been the past 6 months.

Market makers

Perhaps the only other individuals who have the ability to test and audit volume numbers are market makers.  This could be a HNWI or a coordinated group of day traders consisting of as little as a few bored housewives who have money to burn (e.g., xiaosan).  What a market maker could do is video tape the entire buying and selling of chunks of 30-50 or more BTC to see whether or not the buy and sell orders are filled (e.g., if the liquidity does not exist, the orders could not be filled).  Note: this type of empirical activity can only be done going forward in time.  Unless you have access to a Psychohistory device, there is no way to verify who was fibbing in the past.

If you are willing and able to fulfill this pro bono role, you could test out volume claims at the three exchanges listed above throughout the forthcoming days and weeks and report your findings which would either way qualify one variable known unknown.

In fact, it would be in the exchange owners best interest to implore investigative journalists to  randomly place and fill buy / sell orders throughout a series of video taped interviews.  Specifically, large orders at several random hours each day (that are unannounced to anyone at the exchange).  This then could be repeated over a period of weeks to prevent any kind of rigging (e.g., exchange owners depositing and withdrawing cash simultaneously as known trades occur).

Finding volunteers for such a task would be difficult but it would likely work with roughly $100,000 based on current token prices (~$750).  Any large trader (who is willing to show you the their trades) could tell you whether the market volume is legitimate.  And ultimately, if you can fill a $100,000 trade, it is legit to you, regardless of what fakery the exchange operator may be doing.

[Special thanks to David Veksler and Scott Freeman for their thoughts and comments constructing this post.]

  1. To clarify, this activity is not related to the actions of Bernie Madoff.  He committed fraud and violated his fiduciary responsibilities but not by using an internal desk at an exchange.  On the other hand, if the exchange utilizes its knowledge of customers book orders to front run, this could bring legal liabilites to the exchange.  Nor does this imply that HFT systems (small or large like the new one built by the NYSE in New Jersey) tied into cryptotrading are axiomatically front-running as they are unable to see other customer buy/sell orders.

Why Huobi purportedly has higher volume than BTCChina and OKCoin

[Note: I posted an earlier draft at reddit, below is a revised and expanded edition]

For those unfamiliar with Huobi, it is now the largest BTC exchange in China doing roughly 40,000-80,000 in volume a day (versus 4,000 at OKCoin) – though these numbers could be suspect (see the last section below).  Earlier today I spoke with my friend who is building an exchange in Shanghai who explained the volume discrepancy.

The way the current exchanges in China are nearly all set up is that all of the trading is actually conducted using the CEO’s personal bank account.  That is to say, none of the exchanges (at first) utilized a corporate account.  At some point this past year the big exchanges managed to switch to corporate accounts in some form or fashion.  So on top of the 3rd party payment provider ban issues last week, the CEOs at the big exchanges (probably) expect some kind of crackdown on personal accounts so they are trying to go completely legitimate and avoid the risks associated with personal liability.1

Thus Li Lin (CEO of Huobi) is shouldering a great deal of risk that neither Bobby Lee (BTCChina) nor Xu Mingxing (OKCoin) no longer are willing to do any longer (see below for several reasons why).

The other reason for Lin’s success is that he has an individual account with each bank (ICBC, BoC, ABC, CCB, SPD, etc.) so his system does not utilize an interbank transfer (other exchanges may have used that same method as well, I do not know). Again this is largely due to the current legal policy (which has existed for as long as I lived there) in which you cannot just move money from a corporate account to a personal account without a fapiao.2

Note: if you are a big trader, right now you would want to use Huobi to buy BTC (as it is the easiest/fastest way to do so) but use BTCChina for actual trading (due to its API/bot functionality and features).  Why?  Because ceteris parebus as the big exchanges get closer to zero liquidity then there will likely be larger arbitrage spread opportunities.3

Personal and commercial accounts

A reddit user asked, “so the government restriction doesn’t apply to deposits sent through a CEO’s personal bank account?”

As of right now, it does not. But the CEO part is not necessarily the linchpin as outlined by some specific bank policy. The exchanges use the CEOs personal account due to liability issues, how bank transactions take place (personal versus corporate) and how corporate structures work in China (e.g., you do not ask the intern to use their personal account even though it is roughly the same as the one the CEO uses). The People’s Bank of China (PBOC) could restrict that directly if it chose to irrespective of whether or not you have a fapiao (invoice).

Which brings up another overlooked issue entirely, why is a fapiao necessary? Basically if you want to move money from a corporate account to your personal account, you need to have a “chopped” (印章) invoice for each transaction.4 Even if you own the corporate account, in China you have to present this fapiao for each exchange. You can imagine the logistical and paperwork burden that would place on say a bitcoin exchange that processes tens of thousands of transactions a day.  China Briefing has a good a explanation of how a fapiao works.

And as mentioned earlier, one of the speculations right now is that Bobby Lee and others believe that there will be a crackdown on personal accounts and that is the reason why they stopped doing it (you would have to ask them though).

I personally would never allow my account to be used like that as it really puts you in a bad legal liability position if someone you sent/received money from ends up doing something illegal. You could be held liable as accessory to whatever crime or even more directly, enabled money laundering to take place (depending on jurisdiction).5  But again, this is a personal preference and there are obvious huge financial rewards for taking that risk right now.

Outright banning

Another reddit user asked, “why would the government not try to close personal accounts used for BTC exchanges?”

The answers are completely speculative (unless the person you talk to works for the PBOC).

Ultimately the PBOC has the authority to ban cryptocurrency exchanges on the mainland and even ban the commercial use of it. But they have (so far) chosen not to. This is not an accident and again let there be no doubt that they can ban nearly the entire ecosystem within China immediately (e.g., exchanges, merchants, POS, even large ASIC facilities).

Why haven’t they?  Perhaps they want to control it which is significantly easier if there are just a couple of big exchanges and not many small ones (there were ~20 about 2 months ago, it is unclear how many there are today).

Perhaps connected members in the PBOC and its peer organs in the Party appartus are indeed making money off of BTC as some have speculated, but this is impossible to tell unless an address is verified.  For example, on a small, distributed 1-1 scale, bitcoin exchanges are essentially untraceable (e.g., act as massive “tumblers“) and the Chinese personal banking system makes 1-1 transfers very easy.

Obviously Chinese policy makers cannot afford to undermine their dollar assets, but they more than likely want a multi-currency world and by creating this additional uncertainty in the FOREX market it encourages currency plurality. That is to say if you are unsure about the USD, you will also hold Euro and RMB.  However, the RMB cannot replace USD now because of capital controls and if that is their goal, the road to adoption is extremely long as RMB settlements account for ~2% globally.6

Padded numbers

According to some news accounts, OKCoin (and likely others) may have been fudging its volume numbers which could explain part of the large drop in recent volume.  This of course is disconcerting in that it hurts the credibility of all exchanges and only adds ammo for critics who claim that exchange operators can do a lot of front running since there is currently little transparency (e.g., who is to say anyone besides the exchange itself is actually trading on exchange X or Y?).

As a consequence, this same friend recently told me how Xu Mingxing may have brought unwanted attention to his own account because of those huge posted volume numbers.

And again, my point about the CEO account link above was to illustrate the operational risks involved with creating financial startups on the mainland.  Prior to the Bobby Lee inauguration, all of BTCChina’s deposits purportedly went to the co-founder Yang Linke.  Perhaps there will be another personal account method used there in the future.  We will find out shortly.  And as long as the customers are fine with it, it is/was apparently much easier in terms of accounting to try this method.  Thus it will be interesting to see how the industry hedges those risks/liabilities in the future and to see what areas the Chinese policy makers restrict next.

  1. The PBOC issued guidelines prohibiting 3rd party intermediaries and payment processors such as Alipay and Tenpay from transferring CNY (renminbi) to and from cryptocurrency exchanges.  This effectively put an end to all mainland based CNY deposits for BTC exchanges.  See Bitcoin Value Sinks After Chinese Exchange Move from The New York Times and Doubling down, China bans transactions between Bitcoin exchanges and 3rd-party payment companies from Tech In Asia []
  2. Again while speculative, the “new” exchange system implemented at Huobi and others may be very low tech and simply involve a person using internet banking to manually transfer and approve all funds.  This is much slower than the automation previously used. []
  3. If you want to cut your teeth programming HFT bot software, you can use the open source cryptrade libraries at git and join the community at Cryptotrader.org []
  4. See Chinese Chops Or Seals from About.com and What is a Chinese “Chop” or Seal? from Yahoo! []
  5. There is no global standard yet, Singapore’s government is taking a hands off approach towards cryptocurrency right now whereas Denmark plans to regulate and oversee its use. []
  6. For an explanation as to why the RMB will not replace the USD anytime soon see this overview with Patrick Chovanec from earlier this year.  I also recommend reading the Debt and Reserves section from Michael Pettis’ note in October.  In addition readers are encouraged to read the highlights of this Bloomberg report on the hypothetical issue of Chinese institutions “dumping” the USD en masse.

Another Brick in the Wall: Link Edition #54

The biggest news this past week has been the huge rise in cryptocurrency prices (BTC & LTC) pushed in part by the Chinese exchanges.  Both BTCChina and OKcoin now have higher volume/liquidity than any other market and region on the globe.  To give you an idea of what that competitive niche is like, check out BTC123 and Hao123 (both in Chinese).

Why it is impossible to profitably mine bitcoin (BTC) with GPUs — but still quite profitable to mine litecoins (LTC)

I recently had a conversation in which someone asked me to help build them a bitcoin mining machine.  I explained that looking at the mining configuration hash rates, they should not bother unless they had access to a new ASIC miner.

The problem is even if they do not have to pay for electricity (e.g., it is “free” somehow) the difficulty rating is rising so fast (double digits at every adjustment) that even a top of the line ATI GPU is equivalent to “old school” CPU mining at this point.  They would get mere fractions of BTC even if they set up two or three ATI 7970s.

For example, check out this bitcoin mining profitability calculator and plug in the numbers… only gigahash (and now terahash) producing ASICs will get anything useful out of it.

A souped-up, overclocked Radeon 7970 will do around 700 Mhash/s for BTC.  So let’s say you connect three of the best Sapphire Vapor-X, they are listed at $440 a piece.  Factor in the rest of the system (cheap hard drive, ram, cpu, stable power supply, milk crate) and you are pushing at least $1,700 yet only producing 2100 Mhash/s.

Plug that into the calculator, the break even will be >10,000 days because you are only mining 0.0017 BTC a day.  Assuming you did it for 365 days and the rating difficulty didn’t increase (which it does at double digits every reset) you would end up with 0.6205 BTC in one year.  But again, this wouldn’t happen, more than likely you would get less 0.1 BTC the first year.  And nothing at all the year after.  Why?  Click here to see the visualization of the bitcoin difficulty rating this past year.

Again, you would be much more profitable mining Litecoin, for example, if we use that same system you would end up doing about 2100 KHash/s and generate about 1.42 LTC / day (here is a litecoin estimation calculator).  Note: LTC mining is extremely memory intensive, hence the substantially fewer hash/sec.

But even then, this would decline as the difficulty rating increases each reset.  Best case scenario, that rig would get about 400 LTC/year.  The highest a LTC has sold for thus far this year has been about $20, so you could earn $8,000 in a year (assuming you sold the coins and didn’t save or reinvest them).

Thus, it is far more profitable to mine LTC than BTC.

But let’s go back to the 0.0017 BTC you would make if you set up that system today.  Even in the rosiest of conditions, where one BTC was worth $1 million, .1 would be $100k, .01 would be worth $10k and .001 would be worth $1k.

Therefore, even in the most optimal scenario, there is no GPU solution that is profitable mining BTC, even if the electrical costs were free.

One litecoin now worth more than one ounce of silver

Today, for the first time, one litecoin sold for more than one ounce of silver on the exchanges.

On Okcoin it is 132 RMB ($21.38) and on BTC-e it is $20.10 — versus the spot price of silver that is just around $20.

This of course is merely coincidental symbolism but this also begins the countdown until one BTC (~$860) passes one ounce of gold ($1255).

Wonder how long it will take either to surpass the inflation-adjusted historical record of both?

Bitcoin in China: Fall Edition

I’ve discussed BTC and cryptocurrencies and their adoption in China before (here), time for a quick update.

A local channel out here called International Channel Shanghai (ICS) recently broadcast an English-based profile of BTC (and LTC) on its program called Money Talks (click here to watch it).

Overall its a fairly in-depth and accurate explanation of Bitcoin and doesn’t really devolve too much into scaremongering (though it does talk about all of the risks/regulations in the US and elsewhere).

According to the show there are now 14 exchange sites on the mainland that have been set up in the past 2 years (the two it mentions are BTCChina and 796.com).

The show found a professor (Yang Qing) at Fudan here in Shanghai who thinks that the government will be hands off for now because the overall market is very small.

They also interviewed another professor who errs as to why Bitcoin is not money: because there is no physical army backing it up.

Again, it is about 20 minutes and does a decent job of presenting it to the audience without fearmongering.  (FWIW, Bobby Lee, the CEO of BTCChina is the brother of Charles Lee, the creator of LTC who is over at Coinbase now, see this recent Wired profile on him).  Lastly, Jesús Huerta de Soto is name dropped at the end; for those of you unfamiliar with him, he’s an economist who has written a number of books on banking policies, credit and finance.

Regulatory risks, challenges and opportunities of cryptocurrencies in China and elsewhere

On Monday I had lunch with a couple of tech investors based in Shanghai.  We chatted about a number of topics but spent the bulk of the time discussing Bitcoin and specifically Bitcoin-related opportunities in China.  As an aside, a few months ago I wrote a post about the small BTC community in China.

As enthusiastic as I might be regarding the positive merits cryptocurrencies such as Bitcoin and Litecoin offer, I do think that regulatory oversight specifically in the form of Known Your Customer (KYC) and Anti-money Laundering laws (AML) will present serious hurdles for the entire ecosystem.  (Here is a podcast I did with David Veksler back in April regarding some of these challenges.)

In fact, all Bitcoin money exchanges based in the US have closed down and Mt. Gox, the largest exchange has recently suspended US dollar withdrawals for the next couple of weeks.  This is not to say that the cryptocurrency experiment is doomed to fail but it does mean that going forward all entrepreneurs and investors should be cognizant of the fact that the state — globally — has its eye on it.

Below are some links to relevant news stories about various exchanges and money transmitters being shut down/suspended:

In terms of the volume of various exchanges, Bitcoin Charts has an up-to-date spread of the major exchanges for BTC.  And based on CryptocoinCharts it appears that BTC-E has the lionshare of volume for Litecoin right now (~90%).

If you have a VPN or are based outside of China you can listen to a recent interview with Charles Lee, the creator of Litecoin (here was the first public announcement of Litecoin back in October 2011 made by Charles).  And if you are interested in visualizing the profitability and popularity of mining other alternative cryptocoins, visit CoinWarz.

Reader who were wondering who the lead developer of Bitcoin was now, his name is Gavin Andresen.  A few weeks ago the WSJ published an in-depth profile of him as did HuffingtonPost here as well.  Warren Togami is currently part of the core development team of Litecoin, he also works at Red Hat developing Fedora (he put together a LTC fundraiser the past couple months).

Lastly if you’re interested in knowing exactly what FinCEN announced back in March, here is the full guidance notice and the American Banker recently interviewed Jennifer Calvery, the director at FinCEN for her thoughts on cryptocurrencies.
