Investing in bitcoins is like watching a video tape of that basket ball game and betting on how many points Jordon scores. Some people already know the answer, and some don't. There are individuals that own as 1,000,000 bitcoins out of the 12,000,000 or so in existance. More than half the total in existence are owned by less than 100 people. Without any sort of insider trading laws, collusion laws, etc, that makes the market just as fixed as if a single person was setting the price on their own whim. Certainly, you can try and guess what price they will pick and see if you can "win", but the game is fixed. If at anytime it looks like that will change, they'll just pull all the money out of the system and go find another SCAM to steal people's money with.
