If Greece exits the eurozone, what actually happens to the existing debt? And will their currency actually have a lot of value? Just seems like a huge mess and I'm thankful I'm nowhere involved with it. I can't imagine what it's like for everyone involved.
Greece will still have to pay its debt even if they exit the Eurozone, although they will not pay their debt in euro but in drachma. The drachma will inflate and lose its value by 50% since the greek economy is non-existent.
