Congratulations to you OP, that's a big amount of winning and also that's a good decisions to quit in gambling because you already have a profit but before that like what other user said above make sure to withdraw it first in order to prevent such loss. But in my own I don't think so if you are permanently quit in the world of gambling because once you are experiencing a good amount of winning then theres a chance that you will be gamble once again.
Op had really made some good fund and if he decided to quite gambling them I know he is doing that not to lose all 5he money he had won from bet. This is one of the things we need to be very conscious of because if we don't preserve our funds especially the ones we won, then we might finally lost it.
A wise gambler will always uses his winnings to invest especially buying some crypto holdings before the money will finish as usual. Quit gambling if you think you can after making a big winning is wise.
