Probably, for most gamblers who are not addicted, this is not even a trick or strategy, but a standard behavior. In general, using this example, you can see the difference between a healthy person and a patient with gambling addiction. If a person is constantly losing and has lost the entire bankroll, it does not mean that he is addicted. If a person wins (that is, he has achieved his goal) and, nevertheless, continues to play, then, as in the first case, he loses everything, then this person is addicted.
Regardless of the fact that he isn't addicted whereas having loses there's still this need to stop in between the activity cause gambling addiction start up gradually and overtime it tends to grow beyond ones imagination and that's not based on whether the person counter loses or not. Once you can't control your habits even when your getting a win there's still much chances of being addicted. So what I'm trying to say is knowing when to stop is an added advantage and helpful in limiting addiction.
