Cryptocurrency in the news #23

Closing tabs.

A few interesting stories, the first of which is from The Economist, “The dollar’s sterling work.”  One notable passage from the article is, “people exaggerate the importance of the yuan. Just $0.3 trillion of Chinese assets are open to foreign investors, compared to $56 trillion of American ones. That makes the yuan a poor candidate for a global reserve currency.”

As I explored in chapter 13, Bitcoin adopters who continue to claim bitcoin will become a reserve currency usually do not understand how or what foreign currency reserves are.  The Chinese RMB, not bitcoins, has a more probable future as a reserve currency and as discussed by The Economist and others cited in chapter 13 (such as Patrick Chovanec), this is not going to happen anytime soon for the RMB, if ever.

I also recommend reading through “Inside Visa’s Data Center” published last year to give you an idea of the quality and security of their network.  Significantly different (42 firewalls, mirrored center in Midwest) than the cartoon caricature that some vocal “decentralize the worlders” claim it as.

Thanks to Izabella Kaminska and others for a couple of the links.

  1. Interesting that VisaNet in 2013 had the capacity to handle 30,000 transactions a second with 377 servers, or less assuming that some servers are used for the non-payment functions mentioned in the article. Bitcoin has over 7,000 distributed full nodes, but not rationally connected except for the largest mining pools, exchanges and payment processors. Furthermore, VisaNet considers only two datacenters, both located in the USA as sufficiently redundant and geographically distributed, to handle the majority of the worlds payment card transactions. As grand as VisaNet’s datacenters appear to be, they are certainly lower cost than the sum of today’s industrial bitcoin mining datacenters which consume much higher power and must constantly upgrade their mining equipment.

    One wonders how VisaNet can secure their private transaction ledger at much lower cost than Bitcoin secures it public transaction ledger given the 3000x difference in daily transaction quantity.

  2. Regarding digitalBTC, its interesting to learn that this industrial miner is achieving return on investment within approximately four months. Probably there is a short window of opportunity subsequent to the ROI point during which bitcoin can be mined profitably before the relentless growth of difficulty forces the replacement of the equipment while buyers can still be found.

    I figure that digitalBTC mined 2% of the bitcoins generated during the calendar quarter.

    Regarding the depreciation line item, please clarify what I am supposed to see. I suppose that digitalBTC is depreciating capital assets using the allowed method with the largest first year depreciation amount. I would rather know the difference in price between what digitalBTC pays for a mining rig and what they sell it for at the time of replacement.

    I suspect that digitalBTC has a preferred customer arrangement with BitFury that puts them early in the delivery pipeline for new rigs, and makes it more difficult for smaller players, e.g. individual miners, to achieve the same ROI. Additionally, digitalBTC faces competition from more vertically integrated industrial miners that manufacture and mine – thus shortening the ROI duration.
