I intend to stop whenever I already earn my expected profit for that visit or If I lost my budgeted money for my stay. I myself, is very cautious whenever I gamble. I hate losing *even though it is part of the game* but I want it to be minimize so that I could still go home empty handed.
Everybody hates loosing even the site hates loosing their money 
I could roll all day if everything goes smooth and there are times when i am having the supreme confidence when the seed is pretty cool and will have an idea how things goes and when that happens i usually make a good amount,but most of the time i loose my balance and that is what gambling is.
