Lets say you are betting on a coinflip. On heads you get 1,9x your bet (notice the house edge), and on tails you lose your bet.

If you lose, just triple your bet until you win. When you win, you stop playing. The expectation value of this system is >0.

This system never fails. House edge doesn't matter. If the house edge is larger, you just 4x or 5x your bet. If you have very large wealth, the only counter to this system is maximum bet size.
