Paul Krugman:

Stross doesn’t like that agenda, and neither do I; but I am trying not to let that tilt my positive analysis of BitCoin one way or the other. One suspects, however, that many BitCoin enthusiasts are, in fact, enthusiastic because, as Stross says, “it pushes the same buttons as their gold fetish.”

So let’s talk both about whether BitCoin is a bubble and whether it’s a good thing — in part to make sure that we don’t confuse these questions with each other.

Incendiary headline aside, it does seem right that these should be two questions addressed separately from one another.

The Economist:

The original paper that sparked the creation of Bitcoin has since been supplemented by layers of agreed-upon protocol, updated regularly by the system’s participants. The protocol, like the currency, is a fiction they accept as real, because rejection by a large proportion of users—be they banks, exchanges, speculators or miners—could cause the whole system to collapse. Mr Hearn notes that he and other programmers who work on Bitcoin’s software have no special authority in the system. Instead, proposals are floated, implemented in software, and must then be taken up by 80% of nodes before becoming permanent—at which point blocks from other nodes are rejected. “The rules of the system are not set in stone,” he says. The adoption of improvements is up to the community. Bitcoin is thus both flexible and fragile.

Is it just me, or does this entire paragraph reads like the explanation of The Matrix?

Paul Ford for Businessweek:

Maybe Bitcoin’s devotees are right, and it’s the currency of the future. Or perhaps it’s a ridiculous joke—a speculative, hilarious enterprise taken to its most insane conclusion. Given that the founder is nowhere to be found, it feels like a hoax, a parody of the global economy. That the technology used to implement it has, so far, shown itself to be impeccable and completely functional, and that it’s actually being exchanged, just makes it a better joke. The truth is, it doesn’t much matter if it’s a joke or not. It works.
