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.
As for me, it's a good strategy yet it has a bigger risk of losing your funds at the same time. There's no guarantee that you will win higher when you double your bets after losing. Everything revolves around your luck in gambling so there's no specific strategy that could give you an assurance of gaining something after when you bet higher. If you're brave enough to take the risk, be sure that you'll afford to lose the funds that you will be betting.
