It is not a rule that every gambler must follow, but it is a way to avoid losses we might experience when we continue gambling. By continuing to gamble, we can experience bigger losses and even lose all the money earned from previous wins. Every bet does have a 50:50 chance but when we start gambling, our chances of winning will decrease while the chances of losing will increase. And if we are not observant, we can lose and lose so much money that it could cost us all our money if we don't stop immediately.
Taking a short break can also be a solution to avoid loss and reduce emotions or tension after gambling and experiencing loss or even winning. By resting, we can reduce tension and think clearly about what to do because we have been gambling for some time. And during that break we can see how big a chance we have if we still intend to continue gambling so that if the chance is not big, it is better for us to stop gambling immediately.
The only thing that bring this quick conclusion to cash out is doubts and fear. However, trusting in your ability and predictions sometime chase away this self confidence in your own predictions. It's a rule that you must cashout and even, only few gambling platforms has it, there are some platforms that will never give you that option to minimize loss.
I have had games in the past where I cashout and at the end, your initial predictions played well and then it becomes a regret because what this gambling platforms does is that when they give you an option to cashout, your pay out will be slash by 8 or 9 even if you have just two or three games left to be play. They are doing it so they can reduce the amount they will pay you if your prediction went through. I don't like it at all, once a game is stake or wager, I remove my mind from the money because it's has been risked, if it comes home fine and if it doesn't, then we go again tomorrow.
In general I like to enjoy my wins so I withdraw at least %25 of my money that I won from casino to spend it for usual things. But sometimes, if I feel more hungry (or thirsty) for more money I completely leave it away in casino to use later. I would personally suggest everyone to withdraw %25-35 of their money to enjoy life. Then you can return back to gambling. When you never use money that you win, it feels really dull. I don't want gambling to be routine like working, it should be entertaining.
How do you manage to get 25%? Gambling platforms are smart people, I'm not sure of your betting platforms but before you get upto 25% or your deposit, you will either pick to withdraw your deposit with little change or live it, that's what my bookies does all the time because of you are not willing to give them your capital, you wouldn't have there own either. It's either you live the stake u touch or you complete cashout the capital plus some tokens.
