When you have won a large amount of money in gambling, it is better to withdraw it than to keep it in the account, you will feel like continuing to play if the balance is still there, at least withdraw 70% or more and the rest you can play that way you will not care if the 30% money will lose because you have secured the rest.
Gamblers who have won withdraw the entire balance and take a break - well done.
Gamblers with a win and withdrawing their profits leaving only the initial balance - pretty good.
Gamblers with their winnings still want to keep playing because of greed - eventually lose everything and become regretful.
For me 70% is too much to remain in the account because it is an invitation to treat instead If I win big money I will withdraw the money and possibly keep 15% back in the account to forecast more games whenever the need arises and that will be when I must have invested the huge amount that I withdrew. There is a spirit that controls bet when it comes to gambling because whenever you have a substantial amount in your wallet you will be tempted by an unknown spirit to go and gamble and try luck so that is the reason why it is not always advisable to keep a huge sum in your gambling account or wallet because you might end up spending all of them to gamble without knowing.
