WARNING: Taking this conversation out of the monetary exchange systems arena into the political merit arena is liable to end its life promptly (past events being any guide). > http://nakedsecurity.sophos.com/2011/06/21/bitcoin-currency-collapse-wher= e-next-for-digital-cash/ Reading that, it was crashed by hackers and reduced to about zero worth BUT then rolled back by the Bitcoin administrators. Note that every bitcoin carries a complete record of its life history "internally". Hardly hands off laissez faire BUT wouldn't it be nice to do that to eg "a currency that many of the list members use day to day" - or any of the PIGS. Apparently (and what would I know) if G goes down then German and French banks are heavily invested and may fold. And U' banks are well represented investors with teh F&G banks so .... Here we go again ... .. Unless they can manage a bitcoin like intervention. In the "real world" the attempts are made before the event rather than after. After you get only ambulances at the bottom of the cliff, with no rollback allowed.
