Are you going to pay 199btc to the guy who sent ya 0.1btc?

edit: the game ends within 14 hours. This is also kinda flawed since you can just send like 20 bids (0.2,0.3,0.4 etc, and hope noone else does that) before 199K block and it will cost you 40btc to win 199btc. (also don't forget to negate 0.1's guy)
If i was running this game (and had a service where people send their coins aka laundry) I would just double every unique bet before 199K block automaticly somehow.
