Quote from stevegee58:
Actually the big run-up in USDBTC coincided with the Cyprus banking crisis. BTC was languishing in the sub $20 range for a long time until then.
That wasn't greed, it was fear.
The first runup was up to $33 and had nothing to do with Cyprus or any other crises. Sure, it can be used in case of bad economic situation, but the major use of bitcoin currently isn't that...
