If i have a profit in a particular game i usually stop in the game because i believe in playsafe. You know you dont the time of luck you have sometimes Its short and sometimes its long. So to be able win the game playing safe is must. If you see that you get profit goal then stop and play again tomorrow.
play safe is better in gambling in addition to avoiding loss sometimes we may not be able to get profits goals so I think regardless how much profit you get as long as you get profit it's better to just play from bankroll not profit.
@ufaiz50, agree with you, with this strategy it will help one player to minimize a certain lose of a player. and its better to play safe than to lost everything. also, if we only play in bankroll and not together with profit, we may lost some but atleast we have not lost our profit.
