Paul Ford in Bloomberg Businessweek:
One of the oddest bits of news to emerge from the economic collapse of Cyprus is a corresponding rise in the value of Bitcoin, the Internet’s favorite, media-friendly, anarchist crypto-currency. In Spain, Google (GOOG) searches for “Bitcoin” and downloads of Bitcoin apps soared. The value of a Bitcoin went up to $78. Someone put out a press release promising a Bitcoin ATM in Cyprus. Far away, in Canada, a man said he’d sell his house for BTC5,362.
Bitcoin was created in 2009 by a pseudonymous hacker who calls him or herself Satoshi Nakamoto (and who might be several people). It’s a form of virtual cash used to buy goods and services online. Even by Web standards, it’s a strange and supergeeky phenomenon. This is what happens when software and networks meet the concept of currency, when you take peer-to-peer networks and advanced cryptography and ask, “How can I make a new economy?”
There are 10,952,975 Bitcoins in circulation. (With a digital currency you can be specific.) Bitcoin isn’t about to replace hard currency—with a market cap of $864 million, all of it is worth less than what Facebook (FB) paid for Instagram—but it’s bigger than anyone expected. And many people will tell you that the emergence of a virtual global money supply beyond the reach and control of any government is very real and that it’s time we take it seriously. As long as the Internet remains turned on, Bitcoin will be there—to its adherents, it’s the Platonic currency.
