hrm yes 1 BTC on the 98% is a nice payout (1.01020408 + FREE BTC = 2.01020408). Very low risk (ONLY 2% chance to lose! lol). I will have to watch the bet #'s carefully.
It's double your stake back + whatever you win. So if you win, it's +2.01... BTC and if you lose it's still +1 BTC.
But if you lose AND you miss the 10M bet, then it's -1 BTC. That's the gamble.
