Withdrawing part of the money won is one of the best thoughts that can be in gambling, otherwise if you do not do this, we will never make a profit, even from those rare wins that happen in gambling. -snip-
I agree that instead of gambling all the winnings, at least what the gambler does is they can withdraw some of it or all of it if they can. Because in many cases when a gambler gambles their winnings again they will end up spending all of it and that makes them unable to enjoy their winnings. Gamblers should consider withdrawing their money and then they can use it for more important things, with that they can enjoy their gambling and not burden them because of losing the money.
You are right but that depends on the type of gambling you are involved in, for a gambler that is into roll over types of gambling, the rule is to reinvest with the total amount that comes out from each winning this will help the gambler to be able to get good record of how many days he has successfully played and gotten is exact target but for someone who is not into roll-over gambling, the best thing to do is to remove some amount from the profit realized before gambling again so that if their are losses the gambler will fall back to his left over funds and keep trying again.
