I stop when get profit from gambling because have try many time if keep going on to betting all my fund loss, so better left and close all gambling site than withdraw fund before take back by gambling. Many people when reach much profit keep going on for gambling because they think can get much profit again, but when all in least profit earn before loss and have looking money again for deposit. Better manage with your profit maybe half to withdraw and half to use betting again if you can't stop for gambling.
But what you're saying is off from the topic which is about those gamblers who have won against the casino.
It's not about our profit as we gamble and taking it out before they take it back.
