I'd never read that Sept. 2011 Krugman post on Bitcoin that Matonis links to.
http://krugman.blogs.nytimes.com/2011/09/07/golden-cyberfetters/ It is shockingly bad. And I'm not just talking about the "deflation is bad" / "hoarding" angle. That was dumb, but it was a predictable kind of dumb. I'm talking about this:
My first reaction to Bitcoin was to say, what’s new? We have lots of ways of making payments electronically; in fact, a lot of the conventional monetary system is already virtual, relying on digital accounting rather than green pieces of paper. But it turns out that there is a difference: Bitcoin, rather than fixing the value of the virtual currency in terms of those green pieces of paper, fixes the total quantity of cybercurrency instead, and lets its dollar value float. In effect, Bitcoin has created its own private gold standard world, in which the money supply is fixed rather than subject to increase via the printing press.
He thinks Bitcoin's fixed supply is its
only new and noteworthy feature? (And of course, he thinks that feature is a bug.) A first-of-its-kind, global-in-scale, decentralized, digital currency and payment network that enables direct, peer-to-peer, borderless, anonymous, nearly-instantaneous, nearly-free, and irreversible cash-like transfers of value? The first currency and money system in the world which has no counter-party risk to hold and to transfer? The most potentially disruptive technological innovation since the invention of the Internet? And Krugman's reaction is (essentially) "yeah, but how is that any different than Chase Online Bill Pay?" Wow. Talk about missing the point.
