As the questions says, when do you stop? your point of no return?
a. at least double your money, then stop
b. you only stop when you have lost all your bankroll money and then blame the casino?
c. or you are a superstitions gambler, when you have signs like losing 3 straight in a row, then you quit because you know that you're having a bad luck
d. you stop when you are at least break even
I didn't include chasing your losses as obviously you might to continue.
Most times it varies, depending on the mood I am in that day and the outcome of each bet. Most times, I might wanna go with option "a" which is try to double my capital then step. But if that doesn't work out as planned and I find myself in a messy situation, I automatically switch to option "c" I wouldn't actually call it being superstitious, after 3 consecutive losses, I'll be crazy to think the next one is gonna be the break even that I've been seeking. At that point, all I wanna do is just take a break and maybe come try again some other time, and I think that's just about the best thing to do at that point, because you might never just know if that was meant to be your worst losing streak, and you'll definitely end up cleaning out your bankroll if continued...
