Yes that is what happens when you win at 1xbit they say the winners have breached their Terms and Conditions. They are scammers through and through...
LOL
Everyone violated their T&C because they won on sports betting.
Nice freeroll site you are running.
If the player wins, odds go to 1.0 and if he loses in the long run you get to keep the money. If he wins you just void all the bets and give him his deposit back.
You did the same thing to me long time ago.
