I don't know if I was just unlucky or something happened to my bets but I lost 19 bets in a row on x2 payout. I know it is possible to receive more than 19 but this happens once in many bets. I don't want to accuse Wolf.bet of "unclean" things, I was probably just unlucky.
The best thing here is that you played on wolfbet where you can verify your bets and be sure that there is no cheating on the part of the wolfbet. You had the most unlucky time because losing straight 19 bets in a row is rare. By the way were you using martingale strategy ?
