It is a pity that many people, especially those who profess to be religious believe that having one global currency means that Satan is on his way to rule the world. These people are poor students of history, always looking at the now. For many centuries there actually was just one currency, gold and silver. Though different states stamped different heads on those gold and silver coins, they where just that gold and silver. It was the introduction of paper money, a recent invention that gold and silver where replaced. One global currency has nothing to do with the coming Satan, I suggest to going back to gold and silver then people can not just print money. Think about it. Sure they can reduce the amount of gold, but people will quickly catch on. One currency is good for the world, it always has been. Look for evil in peoples morality.
