It can be a wise decision to decide to bet only 10 times a day (or 100 times whatever fits you) and this is the maximum. If you win and it reaches a predefined limit you can leave the site earlier, but should not bet more then previously decided. In this case you can at least limit your losses, but it doesn't impact on the winning chances of course 
That is right. Gambling is for fun and time passing. Just bet for a limited number of time and money. After losing the fixed amount of money, stop gambling to prevent further loss.
