The martingale method may apply if we bet on sports betting and cards. Because at least we have analysis and predictions that don't just rely on luck, but also predictive analysis that can support victory when betting. Whereas in other games such as lottery and slots, I believe this cannot be implemented. Remembering that winning is random, often in 10+ spins, we never get a win even for once. Also if we can win, we could win only 50% or lower than the bet we made. So, don't try to apply martingale to gambling that only relies on luck.
Martingale is dangerous because it requires a significant bankroll to keep you going in case of a series of losses in a row. If you aren't lucky, you'll have to give up and leave empty-handed even if you bet on something where the odds are close to 50/50 like Odd/Even on roulette. Another danger is that the next time you have to double the money to continue the streak, it will be an amount that exceeds the casino's maximum betting limit.
Martingale method is really dangerous if it is used in a chance based game but I also think that the martingale strategy is very effective in a game where skill can dominantly predict the result of the game. Since sports betting relies more on skill, using martingale strategy can really enhance the chance of recovering losses and possibly ending up with some wins.
To many threads like these.
I think, we need action while you are using all of these kind suggestion. Like, make a thread experience gambling for the next 2-3 weeks using the method and sharing us the progress.
I more happy to see thread like these, rather than to much theory.
This is an interesting suggestion but obviously, each person will have a different result when we talk about winnings but if we talk about the effect of the listed suggestions by @OP, I believe it will have the same result as responsible gambling. But there is no way to protect our bankroll but to prolong them, since at the end of the day we will end up losing them unless we quit while we are still in profit.
