When has achieved profit of about 10%, then i immediately get out of casino. Because i realize, if i keep playing can be sure i will lose.
This is good, and we can make one target once we reach that amount we must stop our game. Then only we will see profit in gambling. Otherwise gambling always give us only loss we will never make a profit. I will not make any target, but if I feel that I am losing more games, i will stop my play. And suppose if we win multiple games that day I will not play more games. I will stop my play and withdraw my winning amount.
Do not ever hope that gambling game can make us become rich. I agree that when we already get a few percent profit then it's better to stop and continue later. We all know that gambling is a risky game and is also dependent on luck, so do not expect to make a profit again once we've gained the advantage before. Believe me everything can turn 180 degrees in the gambling game.
