Congratulations!  You see the problem.  You can't get away from unstable currencies. The other problem is that the US will shut down anything that appears to be providing a replacement for the US Dollar.  Once a token or medallion or gift certificate or whatever starts being used outside the confines of one business or one network of businesses, it will be shut down, quickly.  It happened with Las Vegas gambling tokens.  Another more recent attempt was with the Liberty Dollar, gold and silver coins and certificates that not only had precious metal backing, but whose proponents encouraged taking them to retailers and paying with them as if they were US Dollars.  There were other problems with this idea, but it was the competitive stature of the Liberty dollar that got the headquarters raided and the main site shut down. Basically, all signs point toward dealing with currencies and their state of being systematically eroded over time.  If you do find one that appears to exist, be wary, because the rules can change at any time, and the "money" will be nowhere near as liquid as a proper currency.
