When do you stop? Do you have a daily limit or something?
Thisi is fighting for your self. You have to have a self descipline and goal oriented to know your limitations otherwise you will lose.
It is easy to know that, the first time you lose for consecutive times after you win a big price, that is the time you need to stop or else you are going to have nothing. The gambling site is just going to let you win in the first time as a bait, for you to think that you could really make money out of it, but the truth is not, then you are going to be addicted, and that is the time when you have to stop gambling or else you are ending up a broke person.
