Many times, I have seen that most gamblers use to make the mistake of leaving their winning in the casino, even when the money accumulated is already huge enough to offset them into something better but choose to risk leaving it in the casino where there are possible tendency of gambling away the entire balance just with just one temptation.
You're right most of the times that happen and the gamblers really don't care much about leaving their winnings on that casino's wallet. I believe one should withdraw the winnings and invest those in an asset for sometime if the winnings are already high and when makes some profits from that asset then comes back to the casino and start a new gambling session again with some money. That way one will never have the temptation to gamble more or earn a lot of money by putting all the winnings at risk.
We should withdraw the money when we have won a lot and the amount has reached the minimum withdrawal limit. But most people will be tempted to use the winnings by gambling again to double the money. This has become a common mistake that many gamblers make.
We must be able to avoid things like that and use the time to withdraw the winnings. It is also to prevent the desire to continue gambling. We must learn to control ourselves so that offers from casinos do not easily tempt us.
Withdrawing his winnings and investing it in other things, such as investing in Bitcoin, is one way to grow his money. And that is beyond gambling because we are not gambling on that investment. And when his investment has made a profit, he can start reducing his gambling activities to focus more on his investment.
I think that it should be a habit that gamblers should discipline themselves on to make sure that the moment there is a big win, the money should be used to invest or buy something that is worth buying. This will encourage gamblers to always withdraw their wins after they have accumulated it in their casino wallet. It will help to reduce losses.
However, if that gambler thinks that he must always gamble, then he can leave a little amount in his wallet to gamble whenever he wants to because it will be impossible for a gambler to win big and quite gambling immediately. This is rare, since they will think that they can win a bigger amount than the first one
