Maybe you should start reading how it works first before betting actual money on the game?
Freebitcoin betting is not like betting at a bookie where you will win at the odds and payout when your bet confirmed. Odds shown are estimated, and depends on how much other players bet.
FBC's version is called parimutuel betting. Everyone bets on the different outcomes. The losing outcome money is shared to the winning outcome, divided by your winning share. So, for example:
2 people bet $1 and $3 each on Outcome A = $4. 10 people bet $1 on Outcome B. =$10
Outcome A wins, so the 2 people win a share of $10 to a 1:3 ratio.
But of course, FBC takes a commission first.
