In particular, if they decide that they want to stop using the Euro as their currency, and have their own currency, how would that work?
Since greece euros are the same as other european country's euros, how would they regulate who gets to convert their euros to greece money? And would they just arbitarily set an exchange rate? Cause if they were too generous, wouldn't everyone in Europe be wanting to convert to Greek dollars (well whatever the name of the new currency) and if they weren't generous enough, then everyone in greece would just hang on to their euros?
Would like to hear examples of this in history. Like a country that was using a shared currency, deciding to use their own currency.
