In short, is the martingale strategy in betting in such gambling games such as roulette and dice do really is effective strategy? For example, what if you are winning, and every time you win, you double your bets, and basically apply the martingale strategy, which is to double your bet when you lose.
Would that make a huge impact to your funds? I haven't tried it so far, but for me, I don't that is really effective as if we lose, we aren't really going to win right after, because there is still a possibility of losing once again.
Unfortunately, but doubling the amount you bet after each failure is a very risky way to reduce your risk.
There have been many experiments on this subject and from what I remember there were situations in which there was a series of more than thirty hits of the same color in roulette. Even starting with a symbolic amount, to secure such an unlucky series financially, you need to have incredible assets.
