Canadian $ dollar!

The US dollar is hard for any currency to compete. It is the world's global reserve currency. Based mostly on trust. And that the US economy is still the "600lb gorilla." Even though technically the EU is a bigger marketplace? They stumble about worse than US if you can believe that.

So what does that all mean? Take a $5 dollar bill. And go into any bar in the world and say you want a beer/drink. 9x out of ten you are getting a drink. No other currency even close to that. US dollars are just more sought.
