Speaking from experience, you must be careful when you are winning because it comes with a lot of temptation to continue playing. Gambling has a way of giving you money and taking x5 back from you, this might include the money you have worked hard to get. Losing your hard earned money isn't really pleasant and it might ruin you mentally if it happens continually. It's important to take breaks from it when you are winning Because if you keep pushing your luck you might end up losing everything you have won .
You are right and I agree with you that it will take the return of 5x which a users win from gambling on any gambling site. So, a gambler must have to be careful while gambling, and also at the same time the user should have a fresh mentality and must not have any physical or mental pressure as it can be turned into a loss for the gambler.
