I tried out Bet King today. 293 bets. 293 losses. I won't be back.
Lol, did you made those 293 bets with high multiplier like x500 x990 or more? If so, it is a normal if you lose all your bets. Even you can get those 293 losses with x100..
But it would be crazy if you lose that bets with x2 multiplier.
Look at the post above yours. His win chance was roughly 1.45%, so he was expected to win roughly 4 times over the course of his run, however it looks like he might have had a little bit of bad luck.
