When you guys are gambling and already doubled your bankroll, do you still play with the whole money you got or you take away half of your bankroll and start playing with your profit or not?
The safety way is play with your profit, because if you lose you still your money left. But if you confident with that bet and want high profit badly, you can go all in, high risk high return. I prefer play with my profit though.
Yes you had said it right, that will be the best choice and wise move if you are going to play your profit. Because if you are not going to use your original balance but only with your profit, then you are fine because you are still on the safe haven. You don't have any regrets whether you are going to lose with it.
