I remembered a topic that was treated in the past that says that the real winning in gambling is when the gambler has withdraw their winning, that's true, it's wise for a gambler to always make sure that they archives something meaningful with their winning from gambling, that's if they won a significant amount. Some people becomes greedy, that's why they are not able to do anything with their gambling profit.
This is similarly can be related to crypto profits while holding the coin, it's called unrealize profit, if you are yet to sell it then you should know that the profit is not yours yet. Gambling profit can only be yours when you have successfully withdraw it out of the platform, as long as it remain there you can be tempted to try it again, there is this money instinct that will be telling you to try risking the money into another game and before you know, it vanishes in your eye.
It's not that hard to take profit from your gambling, there is nothing that is as a safe as leaving only the bankroll in the casino. If by chance you didn't win anything from the bankroll, you can then try again with another one and the bankroll should be the same and treated like it's normal because once some people have much money with them, to gamble responsibly becomes a problem, they don't know how and when to stop again and that can as well result to more loss.
