Yes, we're not the same with our targets, plans, goals and strategies. Martingale isn't just fitting me and in my experience, I can't push it very hard to keep applying to myself thus, I'll lose more than what I can afford to lose.
I'm not anticipating much with that strategy, and just telling that the first wins you get are little unless you roll with a very high bank roll and from the very start and got lucky to win from it.
As is said few posts earlier, there is no trustworthy strategy for games with pure luck and where another event is not depend in any kind on what was earlier. You can just play for your entertainment, choose your "stop loss" and "take profit". That's all. If you need any kind of strategy - play more complicated and skilled games, like poker or bridge.
