I think for anyone who's not risking big amounts, doubling their money isn't something significant. If you make $0.10-$0.25 bets, like I mostly do, doubling is nothing, right? Sometimes I continue playing even after hitting 100x, but if it's 400x or more, I stop right away. I'm not withdrawing the money I won. I will be betting with them in the future, but not the day I won them. I want to enjoy my winnings for some time.
It really depends on how we will tolerate ourselves after experiencing a big win. Sometimes, if we won big, there's a thing inside our mind telling us to continue gambling because after all, we are lucky. If we stop, we might not win again. That will now test how far we will continue to play.
As much as we can, always put a limit after a big winning. Maybe just risks around 10-15% of our total winnings.
It's ok to gamble again but we should at least enjoy the big money we won.
