With this reverse Martingale system, we increase the stake only when we win. If we lose we keep playing with the same low stake.
You can use the same series of stakes as in the normal Martingale system. For example, for odds of 2, this would be:
After five consecutive wins, the stake is then 32. However, if you lose the last bet of 32, you will still lose all your winnings.
For this reason, you might consider reverting back to the lowest stake after four consecutive wins. In this way you won't see your hard-won profit disappear all of a sudden, like a snowman in the morning sun.
