They can't have their money to buy anything. You talk about bitcoin...
They need some Hawala.
I guess we have the answer.
Q: What effect does Greece leaving the Euro have on bitcoin's value?
A: None
History may find your verdict extremely premature.
This terrible situation validates the core concept of Bitcoin.
Because, Bitcoin will not shut down on Monday.
Bitcoin is money beyond the reach of politics.
Money that cannot be censored or confiscated at will.
An alternative that is always there, and just keeps going.
Under adversarial conditions. Indeed, under any conditions.
Come monday, all Greek banks will be closed.
And Bitcoin will be open for business.
On Monday, and every day, in Greece and everywhere, 24/7.
So, it falls on Greeks citizens and Greek companies to make do with any one of three options.
Cash, or barter, or Bitcoin.
And almost all Greeks will choose cash and barter, but Bitcoin will be there.
And when the world comes crashing down,
Bitcoin is the better option.
And so, the great deluge begins with a trickle.
