Same here, gambling the profits away together with your bankroll is an irresponsible attitude and so it's best to either withdraw them and keep somewhere while you keep gambling with only your specific bankroll. That's how I gamble on sports bet and it's been working for me.
I think people should keep the profit and must avoid to play with it as there are chances of loosing it. People should have total control on their self and must follow some guidelines in order to be a successful in the gambling.
I dont think you would have the chance to do that yourself. If you are not courageous enough to bet your profit. Then, you may not have the courage to place your first bet as well.
