Scenario 2: It's really stupid to bet hundreds or thousands of dollars to win the initial bet.
Logically it is impossible to apply martingale without thinking about limits. I never use this method because I know the limits that must be done so as not to make me run out of money faster. let say 50% increase per 1 bet, to challenge the probability. From here, I am sure that the results will not be better, unless he have unlimited money for gambling, maybe it can reach her turn to win and return to the initial capital or still losing .
It's too expensive. That's what I think about that strategy. Anyone can use it, without any doubts, but sometimes we forget that we are going to spend a lot of money using this strategy. Rich people can use it because they have deep pockets, but average gamblers will struggle with it.
There's no guarantee about what will happen next, and so we play with the smallest amount possible because we try to prolong the battle and maybe hit that very lucky chance to win high multipliers. I might use a martingale strategy in sports, but I will never ever use it in slots. It's too risky.
