The Greek crisis is throwing the country into turmoil. Banks are closed, ATM-machines will only give people small change and coming payments of salaries and pensions are in danger.
Yet there is a working currency, available for all people in Greece. And in the rest of the world: Bitcoin.
Anyone can get a Bitcoin wallet and start accepting payments the very next minute.
Bitcoins may be volatile and there have been problems. But still, Bitcoins are more reliable than the euro for people living in European countries with shaky economies.
Using Bitcoins is also cheeper and quicker than bank transfers.
