Cryptocurrency KYSF: Know Your Source of Funds part 2

ecommerceA few days ago I was asked a number of questions from a reporter at CoinDesk regarding on-chain trade volume; this was a follow-up from some questions back in early May.

A few of my responses were published in a new article today: Dark Web Markets ‘Processed more Bitcoin than BitPay in 2014’

Below are my unabbreviated comments:

Q: How have the recent posts from Coinbase and BitPay impacted the diagram you outlined in that previous post? Has it had any impact at all?

A: The most striking data point from the Coinbase and BitPay posts was what was missing: actual real user numbers.  Neither one of them is willing to publicly say how many monthly active users (MAU) they have which stands in contrast to other fintech companies, financial institutions and “social media” startups they like to compare themselves to.

For instance, even though Coinbase claims to have 2.4 million users/3.1 million wallets, what does that mean?  Are these all fully KYC’ed accounts?  What percent have logged on in the past month?  What percent have actually used Coinbase’s services?  How many simply create an account, deposit $10 and never log on again?

Similarly, BitPay numbers are actually pretty sobering.  We know demographically from both the CoinDesk report and the leaked Coinbase pitch deck that the over 80% of all bitcoin holders/owners are males between the ages of 18-45.  And that the majority of the overall users reside in North America.  Yet according to the BitPay charts, North American volume has been relatively flat the last 6 quarters.

So if the largest group of bitcoin owners are not using their holdings despite a marked increase in available merchants, that is probably not an indication that they are interested in spending their funds and probably see bitcoins as an investable asset than actual money.  BitPay also does not disclose aggregate USD or euro volume.  Startups like to make noise when they are doing good or can show growth; if the value of their volume was actually growing, they probably would say.

And while transaction count in Europe and Latin America appear to be growing, perhaps the collective value has stayed the same (the Latin America numbers are also a bit misleading; it’s easy to show large growth percentages when you start from 0).

Another point about BitPay’s post is that they don’t really say what “IT services” is.  Notably absent from this post, compared with their post in April, is what “mining” related activity is.  Recall that some miners, such as KnC and now defunct BFL were (are) using BitPay as their payment processor.  In fact, in BitPay’s post earlier this year, “Bitcoin Mining” — by volume — represented the largest share of volume processed.  Does “IT services” now include this previously large segment?

Lastly, one number they do not include is the total aggregate transactions by each quarter.  Eye-balling it, it appears for Q2 2015 they processed about 180,000 transactions.  Divided by 60,000 merchants comes to around 3 transactions per quarter or 1 transaction per month per merchant.

In all likelihood usage follows a power law or a 80-20 rule, that 20% of the merchants account for the majority of transaction volume.  My understanding is that Gyft uses (or used BitPay) as their payment processor and since 9% of all bitcoin-related transactions last quarter were related to gift cards, it is likely that the lionshare of this “gift card” activity in the power law distribution is represented by just one or two companies (e.g., FoldApp and are a couple potential ones to look at as well).

Startups like Blockseer, Sabr, Coinalytics and Chainalysis have APIs and address labeling that may be able to tell us more about specific merchant/payment processor activity,

Q: Also, are clearnet tx outweighed by darknet tx with bitcoin? Silk Road and other marketplaces were the first use case for bitcoin, but are they still the biggest?

A: According to a new paper (Soska and Christin 2015), if you look at Figure 5 and the discussion involved, prior to Operation Olympus, six large dark net marketplaces collectively accounted for more than $600,000 in sales per day.  It is unclear how much of that activity was expressly illegal, although the paper does attempt to break down the amount of illicit drugs being sold on the same sites.

During the same time frame (most of 2014), volume at payment processors such as BitPay and Coinbase were relatively flat with a few outliers during days with speculative and media frenzies as well as ‘Bitcoin Black Friday.’

As of today it is unclear what activity is the “biggest” — we would need to aggregate all of the dark net marketplaces and compare that with the reused addresses BitPay uses plus the self-disclosed numbers from Coinbase.

In the chart above, illustrating off-chain activity between August 14, 2014 – August 13, 2015, it is also unclear from Coinbase’s number what a “off-chain” transaction is.  Is it only related to merchant activity?  Does it also include movement between users or with cold storage as well?

Therefore based on past historical trends (above) I do not think that “clearnet” or on-chain “licit” activity outweighs illicit transactions.  One darknet market alone — Evolution — processed roughly the same amount of bitcoins last year as BitPay did.

Q: Do you think consumer volumes will change significantly in the next year – what would it take for this to happen?

A: It depends on what we mean by “consumer volume.”  If this includes both illicit and licit activity, sure, maybe.  If it also includes “off-chain” transactions, then yes, probably as well.  But it is important to note you are not using Bitcoin (or bitcoin) when you go off-chain.  The transparency and auditability trail disappears and a user is now reliant on a trusted third party — many of whom in the “Bitcoin space” have a checkered past on financial controls — to protect and secure your privkeys.

I think we have already largely witnessed what the “killer apps” that incentivize increased usage of on-chain bitcoin activity are: censorship-resistant activities.

If the goal of Bitcoin was to provide a censorship-resistant payment processing platform (the word “payment” appears 12 times in the white paper) then it is safe to say that: dark net markets, casino sites, ransomware and other activities that require censorship-resistance and cannot be globally accessed on permissioned networks will continue to attract users towards it.1

It is my view that the following two laws explain the on-chain phenomenon we observe on a regular basis.  Folk law: “Anything that needs censorship-resistance will gravitate towards censorship-resistant systems.”  In contrast is Sams’ law: “Anything that doesn’t need censorship-resistance will gravitate towards non censorship-resistant systems.”

As far as other “apps” such as sites like Zapchain, while boasting growth numbers, appears to recreate a trusted third party system (e.g., facilitate deposit-taking and MSB activities like other hosted wallets) all while simultaneously scraping content from other sites.2

So Buzzfeed, but with bitcoins.

Does it have legs?  Porter Bibb would probably say no.

In closing, one last comment related to real on-chain trade (as opposed to spam-like “long-chain transactions“) is the recent announcement / non-announcement from TigerDirect.  Jorge Stolfi, a computer science professor in Brazil, probably best summarized the nebulous responses from the electronic retailer:

  • How much have you been making in bitcoin payments? “While Expedia has seen a decrease in bitcoin payments, TigerDirect shared a different story.”
  • How many customers are paying with bitcoin? “46 percent of customers purchasing with bitcoin are new users”
  • Sorry, how much did you say you made with bitcoin payments? “the average order placed with bitcoin is 30 percent larger than the average order.”
  • Yes, but, how much are you selling with bitcoin? “TigerDirect sees the highest volume of bitcoin orders during periods of volatility for bitcoin price.”
  • We would really like to know how much, roughly, you are getting from bitcoin payments. “TigerDirect has still seen consistent bitcoin transaction volume.”

  2. Zapchain uses Coinbase as a wallet provider for deposits — the tipping of transactions is done via via BlockCypher. []

One thought on “Cryptocurrency KYSF: Know Your Source of Funds part 2

  1. Comment on mining economic equilibrium:

    Hi Tim. Thanks for sharing your views. I find them quite insightful (although a bit biased sometimes).

    Anyway, I read somewhere your analysis on bitcoin mining economics. Although I agree with the main rational, I disagree on the conclusions.

    It is certainly the case that in a competitive industry an equilibrium is found when marginal cost (MC) equals marginal revenue (MR). This is particularly relevant in industries with no product differentiation. Bitcoin mining is a textbook example. Now, bitcoin “mining” is a misleading name and some people confuse the product with the revenue: bitcoin mining product is tx clearing and settlement NOT bitcoins. Miners are compensated with two revenue streams: newly generated bitcoins and tx fees. I think we agree on that.

    Tx clearing and settlement is a product with no differentiation whatsoever (customers do not care whether their tx are processed by one or other miner). Thus, as there is competition between miners, micro-economics 101 apply: at equilibrium, MC=MR.

    So, I agree with your assessment on the yearly MC of mining, as it has to be close to the MR per year. At a price of $225/BTC, that is aprox $300MM a year.


    – MC is different from Total Cost (TC). In order to replicate the installed hash power you actually need to set-up the infrastructure. Any argument on the necessary capital investment to build up and maintain a similar network is about both MC and TC.

    – MC is not only electricity, personnel and facilities. MC also includes the cost of capital. The cost of capital is a required return, meaning that you have to compensate additional capital for the risk of certain investments and uncertain revenues (and repay debt). Do not underestimate cost of capital assuming that MC is all about paying electricity bills. Cost of capital is far from zero.

    – MC increases with the price of BTC, that is right, but the function is neither linear nor constant throughout the years. Yearly MC will be very close to yearly MR, which depends on BTC price (and tx fees) BUT ALSO on the rate of BTC generation. Next year, at constant BTC/$ , MR will actually decrease, unless the other revenue stream, tx fees, compensates the difference. You don’t need a MC of $1Tn to support a total BTC valuation of $1Tn.

    – For all these relationships, we are assuming that the mining industry remains competitive. In my view, Bitcoin mining is not a natural monopoly, as some authors argue. The reason being that there are two incentives working in opposite directions: bargaining power AND network integrity. As miners concentrate, it is true they reduce their MC, but concentration also reduces network integrity, which affects MR negatively. It is true that natural monopolies can develop with frictions, but in this space, monopoly is not a possible state (the network would cease to exist altogether).

    – Once the rate of BTC generation is low, marginal tx fees will clear at a level where the network will reach its MC for an amount of hashing power that satisfies demand’s need for security. Market dynamics will find this level for us.

    Anyway, just some random thoughts and personal opinions.
