You could try reverse martingale (this is what I think it's called). Instead of doubling your bet whenever you lose, you double your bet whenever you win. On lose, you'll go back to your base bet.
Let's assume that you've won 8 times in a row and the base bet was 1000 bits.
1000 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 256,000 bits. Your profit grows exponentially. It's not necessary that you stop when you've won 8 times straight, you can stop whenever you want. The more streaks, the more profit you'll get. I used to do this in BustaBit but I usually do it in a lower multiplier so the chances of having a winning streak is more than when the multiplier is at 2x. I don't actually advice this to gambling sites in which you can get a lot of loss. If you don't think the site you're playing in doesn't make you win in streak, then don't do this method.
This may be the only strategy I've heard of dumber than regular martingale.
So you double your bet on every win, how do you take a profit?
Start with 10 bets
Bet 1 win, next round bet 2, lose you have 9 left.
Bet 1 win, bet 2, win bet 4, lose, you have 9 left
So now instead you end up -1 unless you win enough in a row to hit the max bet?
