That's easy. I cash out after every single win, or every single session.
If it's sports, say I bet on a coming UFC match, I cash out after the match, no matter how much it is. That's unless I have something important to bet on then I make the second bet and cash out the rest. I don't hold money on platforms.
If I decide to play a game like crash, I'll cash out when I finish playing. It helps me manage things, keep it tidy and stops me from coming back the next day to check on my funds.
That's a pretty good strategy. Some people quite often forget to withdraw their initial capital, and some of them don't even cash out their winnings at all. It must be admitted that this is quite difficult to do if you are too ambitious in gambling, in my opinion it is also included in one of the strategies to avoid losses after winning. It is very good if you do it in a disciplined manner, because in gambling we must have limits.
Actually, it's not a problem to keep money on the platform if the amount is small, the most important thing is that the platform has a good reputation, but it comes back to each person point of view. Gambling for fun, by managing the budget properly can reduce risk, and that's the best way to be comfortable in gambling.
