This method I made and it gets me really well on the game. what you wanna to is this:
Play with $5 on 49% double the money x2 every hit
If you lose increase the bets x2 to recover the lose:
Lose $5 >>> Bet $10 > Lose $10 >>> Bet $20 >>>>> Lose $20 >>> Bet $40 >>>>>> Lose $40 >>>>> Bet $80
Hit! get the $80 Bet $5 again and if you win you continue and continue to make $5 untill you lose
and increase your bets to recover
you will never have 10-15 times you miss bet on %49 so you will always recover your money back
and hit hit $5 after to make profits
This is simply martingale and it seems you are kinda new in gambling. To tell you the truth you can have 20 or 30 reds in a row or even more that could make your balance into zero. No matter how big your bankroll, martingale will drained it if you play for a long time. It's the worst strategy.
