The fact that some people profit from a con doesn't negate the fundamental nature of this zero sum game. Everyone can't win. For every winner, there must be losers of an equal or greater amount.
Finding more/bigger fools can be fun and profitable but it is not building or creating any sort of substantial real world *value*. The only *value* in this game is that which was created from nothing or obtained from other misguided players. Common sense should tell you that to nothing it will eventually return. Eventually, lots of people will have to be informed that the only *value* they hold is a few electrons and a broken dream. The tricky part is figuring out *when* this will occur.
