I guess that people in US and other big countries with strong currencies don't really understand that there are smaller fiat currencies and these are actually used. I wonder how often you have to convert your USD even when traveling, last time I was visiting Africa I remember most just accepted USD or euros directly even though the countries had their own local currencies.
