Im also a type of person that on the moment that i do able to make up some winning in gambling then i do always consider out on taking it out or make withdrawal and buying up something on which i do want or like.
Just as a mental exercise, imagine that all the casino players in the world, when they win, if they withdraw immediately, I am sure that cases of addiction would decrease substantially, and there would be fewer cases of addiction, of course this applies much more to online casinos, because physical casinos, if there are winnings, are withdrawn immediately without so much complication.
I always recommend withdrawing as you win, otherwise it is very difficult to control that money, because it is always spent, whether you want to or not, you can say that you are going to play and bet this minimum amount and if you get excited, you lose it all and that is not the idea.
