That's correct. Withdrawals are true winning of gambling. Something similar to net profit!! A Gambler can win a lots and then can loss a lot. But the fact is, how much withdrawable fund remain to him, at the end of the day and how much fund he already withdraw in his bank account. If he doesn't withdraw anything, then commonly there is a chance to lose it back again. Maybe he has to redeposit the fund again after loss all fund which was available in gambling website but there are some difference. When you have money, you desire to bets more and stake higher but when you have lower amount of funds, then its easy to control yourself from placing bets randomly. So i support the withdraw system instead of keeping all the fund in gambling website. Although its all about mentality, self control & self discipline at the end of the day
If a gambler has no money after gambling for a long time then it is just a waste of time although gambling is not recommended for the purpose of earning money. But there are some gamblers who are not willing to enjoy the winnings. They are more focused on increasing their bankroll as much as possible and it is imperative for them to withdraw money otherwise they can lose all their money in gambling at any time. A gambler should share his winnings. If he enjoys a portion of his winnings and save a portion as emergency fund, he will receive money at any time. There are many gamblers who have profited from gambling but do not have money at the time of need. To keep his own fortune safe, of course, if he withdraws that money and invests it elsewhere, I think that gambler can gamble smoothly in gambling life.
