The dream of a universal currency isn't new. Before credit cards and digital payments dominated finance, gold served as a natural global currency. Countries backed their money with precious metals, creating a simple system everyone understood - though it left governments with little room to manage economic ups and downs.

Everything shifted after World War II. In 1944, representatives from 44 countries met in Bretton Woods, New Hampshire, with a bold plan to rebuild the global financial system. They effectively made the U.S. dollar the world's go-to currency, promising to exchange dollars for gold at $35 per ounce. Other countries pegged their currencies to the dollar, creating the financial pecking order that still largely exists today.

Fast-forward to 1999, when Europe launched perhaps the most ambitious currency experiment in modern history. Several nations retired their traditional money - goodbye German mark, farewell French franc - and adopted the euro. This wasn't just about making travel easier. It aimed to create a unified market that could compete with economic powerhouses like the United States.

But the euro's journey hasn't been smooth sailing. During the 2009 financial crisis, Greece's struggles highlighted a crucial weakness: sharing a currency means sharing problems. When Greece needed to adjust its currency value to manage its debt crisis, it couldn't - that power now belonged to the European Central Bank, which had to consider the needs of all member countries.
