Why does Greece have the euro currency?

Greece adopted the euro currency on January 1, 2001, becoming the 12th member of the eurozone. They joined because they met the European Union's convergence criteria, which means they had a low inflation, low debt and sustainable deficit, and a stable exchange rate as agreed by the Maastricht Treaty. By joining the eurozone, Greece aimed to improve economic stability, reduce transaction costs, attract foreign investment, and potentially enhance economic growth and competitiveness.
