As long as you win you cannot calculate how much your winnings or your looses but when in terms I have a huge amount of looses ,I stop and rest because getting avoid to get addicted on playing gambling too much.Gambling is for fun and I dont want to waste my time or money on it.
In fact its easy to monitor your losses instead of monitoring your winnings because everytime we won, we still loss in the end. Gambling makes pleasure for you, but at higher cost specially when doing it without any goal. I won before but thats it because I know when to stop and to secure some profit.
