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 ?
When you bet on martingale, it is normal that you may not realize 19 times in a row win as well. If you bet on 10 satoshi per bet, you are going to win 190 satoshi when you go 19 wins in a row, not really a ton of money right? But, when you lose 19 times in a row and start at 10 satoshi and double it every time you gamble you are going to end up at 5,242,880 satoshi or better yet 0.52420880 bitcoins, that is over half a bitcoin at the last bet and of course a ton more until you reach there, almost one bitcoin lost, and you only try to win 10 satoshi when you recover it all. So, it is understandable that you may not realize 190 satoshi won thanks to 19 wins in a row, but it is also easy to calculate 1 bitcoin loss when you go 19 losses in a row.
