Over the last 2 or 3 weeks we had a guy at Just-Dice running 40 bots, all betting dust at 9% chance of winning, looking for long losing streaks. When a
bit bot hit a streak of 100 or so losses in a row, it would stop and alert the guy, who would then take over and bet at 9% manually, increasing the stake by about 10% each roll.
It worked very well for 22.5 million rolls, and then this happened:
Yet another great example of how martingale works great until it doesn't!
Here's the losing streak - 163 losses in a row at 9%:
