The banks are closed and Greeks unable to buy Bitcoin.
so they still can take a tiny portion of their money and buy bitcoin with those
but they will probably need that amount to survive, nobody in their right mind would buy bitcoin instead, seeing the utterly critical situation
Even if they buy bitcoin, who is going to exchange them, still large population of Greeks unaware of Bitcoin, for instance.... old and common people, it is a long procedure that to first explain about Bitcoin then how it's works and other things to them.
they do not need to exchange them, they need to wait first for the price to rise at a very high level , and then they can exchange them via localbitcoin or by going abroad, if you had a tons of money in bitcoin, and you can not exchange them locally, wouldn't you go abroad for it?
