It's the basic tenant of gambling and risk itself, it's the unknown, so if you don't want to risk then cash it out. However, I will tell that you should not feel that regret in the end because you obviously doesn't have the courage to continue with the game and see how far can you go, that is a lesson learned from us. So there is the advantage and disadvantage of it and at the end of the day, it's your decision to stop and take profits.
But at least though in sports betting, you have control, and maybe think logically. In crash, there is none, it should be instant as before you knew it, before the multiplier crashes. Also it's skills vs luck, in sports betting, there is skills that's why again as I have said, you have enough time to think about early cash out.
So for me, there's a big difference between the two.
