As long as you do not use all your profit, I mean as long as you keep some of your profit and use it partly to gamble, that's ok. It's your right to use all your profits, but when you've won a profit, why not save some? Would not it be a waste if you lost again? Because you've saved some.
It is not okay for me because you are going to waste it. Most of the time we are going to lose it after we win so no point to play with our profit. We should just keep everything and come back with a fresh start however this time make sure that you are not playing for profit but for fun. By doing this way , you are not going to lose huge amount
