Somewhere I heard that, cyprus was a wealth heaven, during the crisis the wealth was exported using bitcoin. I don't know if would be the same scenario with greece.
Nothing really needs to happen inside Greece, it's the rest of the world speculating about what can or cannot happen that can drive the price nuts. Now more people are aware on Bitcoin and what it can do vs back in the day with Cyprus, this only means the potential bubble could be bigger, hopefully setting a new higher ceiling (every bubble will set a higher ceiling pretty much add infinitum until like 2030 or so when the inflation aspect of BTC starts being tiny).
