Greece, do what you got to do!
Don't get your hopes up with a Greek rebellion or something. Bitcoin's value is definitely >250 but that isn't necessarily related to what Greece may or may not do. IMO it's bad pump material.
I think a grexit would definetly have an inpact of Bitcoin his value. Not only Greece is participating in this rise, also traders from outside Greece will buy on speculation.
