https://btc-e.com/betsI really don't understand this. They are letting you bet on what the price of bitcoin will be in 5 minutes. How is this fair at all? Could a whale not bet and then buy/sell to take everyones money?
It's easy, win your bet is determined after 5 minutes since the bet was made, if you bet buy then the final result after 5 minutes bitcoin prices must be above of your bet and so also for the reverse.
sorry if i'm wrong, for to not wrong you can check on their site how to play these game.
