Yeah that's a wise decision, instead of completely quit when you've achieve your target, it's better to leave some funds to gamble more when you withdraw your profit. If we always discuss greedy during win and lose, but someone can be greedy when they want to withdraw their money, they're greedy to take all the profit.
Sometime isn't always about money, but we also need to spend time to kill our free times.
I agree with you. Personally, if I win a bet, I choose to keep my winnings, and manage my emotions and finances well so as not to become a gambling addict. It's not all about money and winning. A person needs to know their own limits. When you withdraw your money and at some point you want to gamble, you will definitely make a deposit again. I don't like dealing with that kind of thing. If I win, it's better for me to enjoy the win by not making another deposit that will harm my finances.
