Actually it can be kind of fun...like a game of chess. You research the exchange rates of the various currencies until you get the combination with the return that you like. You start off with a small amount of money (e,g, $50.00) to test your theory, and to see if your research works. If it works you can increase your funding to whatever level you like. The return is fast. When the exchange rates turn against you it is time to begin new research.
