I can recommend a crash game you can win 50 times your profit in just one bet if you're lucky but it's also the fastest way to lose your bankroll you have to be fast stopping the button here, and don't you employ martingale here I tried using martingale and I lose all my bankroll, this can only happen if you're lucky, in reality, you cannot win all the time and you cannot bring fast profit on little duration, you can do try it on 10 bets and it can get the best result.
