I don't understand why people can't see it's all one big pyramid scheme. The early 'adopters' pay small amounts of money for a big percentage of the total amount of 'coins', and the late 'adopters' pay large amounts of money for a small percentage of the total amount of 'coins'. And once people have it, they have every incentive to get as many people to buy it as well, because only then they profit. A blanket ban is a good idea. This cancer deserves no place in the economy.
