Will Bitcoin benefit from the current crisis?

There's lots of speculation that the rate of adoption of digital currencies may increase more rapidly as a result of the current crisis in Greece.

CNN makes the case noting:

"The world's largest Bitcoin exchanges tell CNNMoney they've seen a surge of business from Greece." and

"Ten times as many Greeks are registering to trade bitcoins on the German marketplace Bitcoin.de than usual, according to CEO Oliver Flaskaemper. Bitcoin trades from Greece have shot up 79% from their ten-week average on Bitstamp, the world's third-largest exchange."
