I can understand; as gamblers, we get tempted to place bets. The best way to counter this is to set a profit limit or target. Once the target is achieved, make the withdrawal. If you keep your balance in the casino, then you will eventually get the temptation to place a bet and will continuously want to make more money. Hence the best thing is to just withdraw the funds after a certain amount is made in profits. Withdraw the initial amount you used, and if you really want, then gamble with the previous game’s profits.
