Wanna make a quick million? Here's how:
Greece is going to be VERY Euro hungry for the next 3 months. Fly to Athens with a big bag of cash. All Greek people having relatives in foreign lands (with bank accounts) can send you bitcoin. You pay their relatives in Euros. This remittance operation would be insanely busy in about 5 days. You'd need a courier and body guard each day flying in with new cash.
Instant millionaire.
It is supposed that the relatives of Greeks which lives in foreign lands have bitcoins. I think that Greeks doesn't know yet bitcoin. Even their relatives which live in foreign lands. Then you must have a cargo with euro to give to the Greeks. I don't have those. So, for those two reasons for me and for everyone this operation is mission impossible. Ah ..... forgot. Not for Tom Cruise. Him can do it. If you know him you are very lucky because he must need collaborators.
