And no matter what you do that losing streak will always appear as that is how probabilities work, after all the more you double your bet and the more you use the martingale strategy the more likely it becomes that you will suffer a catastrophic loss.
In gambling, martingale strategy is useful, but if the luck is not attained, the loss is would be far worse and more significant than playing without it. I can not encourage anyone to use martingale strategy while gambling. But it can be useful in some useful games in casino, but I find it not useful in many games, especially those with odds lower than 1.2 or any odd that if you lose four or five times, more than 2x is not guaranteed.
The gambler's emotions can go up and down along with the wins and losses he experiences so if he can't control himself, he can get stuck in a situation he doesn't want. His losses would also be even greater than before, especially when he deposited more money into his account just to continue playing. But that will not prevent the addicted person from depositing money. They will continue to play if they have money in their account or wallet.
This is absolutely true, the best for addicts is to just tell his people, let them know about it and how to cure himself of the addiction. But some people are addicted and they still think luck could come, but failing again and again in money more money losses.
