Bitcoin is a classic private currency scam. It fails to offer stable values, security from theft, privacy from government and ease of use. With prices near $17,000 per bitcoin (Dec. 2017), it is in a huge speculative bubble. It has enormous problems with transaction bottlenecks, transaction costs, and electricity usage compared to alternatives such as Visa.

- "My take on bitcoin is the standard boring economists' take: bitcoin and other cryptocurrencies are the mother of all irrational bubbles... However, as we see with bitcoin, which isn't driven by any kind of fundamental economic value, as it pays no dividends and has high transaction fees, bubbles can happen and markets aren't that efficient."

And that is one reason -- among others -- why I expect the value of Bitcoin to fall -- a lot."

Which is fine if you're a Libertarian, but I tend to take the stance that Libertarianism is like Leninism: a fascinating, internally consistent political theory with some good underlying points that, regrettably, makes prescriptions about how to run human society that can only work if we replace real messy human beings with frictionless spherical humanoids of uniform density...."

If, say, Google Cayman Islands were to start GoogleCoin, and announce that it would always stand ready to buy back GoogleCoins at a fixed real value, it could make a (small) fortune and, I think, eliminate BitCoin’s business in a month…

Bitcoin is Beanie Babies for Libertarian Nerds
It is really very satisfying to see the same idiots who call Social security a ponzi scheme lose thousands of dollars in an actual ponzi scheme. [bitcoin]
It is unfortunate that the kind of computing Bitcoin pioneered has been given the name "cryptocurrency", and has been associated with all sorts of technofinancial scheming. When you hear "cryptocurrency", don't think of Bitcoin or money at all. Think of Paul Krugman's babysitting co-op. Cryptocurrency applications deal with the problem of organizing people and their resources into a collaborative enterprise by issuing tokens to those who participate and do their part, redeemable for future services from the network. So they will always involve some kind of scrip. But, contra Bitcoin, the scrip need not be the raison d'être of the application. Like the babysitting co-op (and a sensible monetary economy), the rules for issue of scrip can be designed to maximize participation in the network, rather than to reward hoarding and speculation.
Steve Waldman, "Econometrics, open science, and cryptocurrency"
I don't understand. How did this unregulated, imaginary currency invented by an anonymous hacker and backed by the full faith and credit of YouTube comments ever go wrong?
