On the other hand, that statement has 4 citations. To modify it significantly (and have your edit accepted) you'd probably have to cite at least twice as many similarly-famous "commentators" that say otherwise. Bloomberg and Krugman are pretty big names, and there aren't that many opinion writers of their reputation that have endorsed Bitcoin.
A couple of Keynesians who believe that the economy needs a constant pumping of artificial credit to avoid coming to a screeching halt don't like a currency with a fixed limit? That's a shocker.
I didn't say it was shocking, and I certainly don't agree with them, but to my knowledge I've hardly seen any libertarian/conservative economists endorse Bitcoin, which is why I was saying in the mainstream press right now it's still not regarded very highly. If you do know of any well-known economists who have praised Bitcoin, I'd be sincerely interested in reading their opinions. Perhaps I just haven't looked hard enough.
