Did this happen to anyone else?
Usually the problem is when depositing money to the exchange from the casino not the opposite and I have never deposited money from the casino to the exchange or maybe I have but only a few times but after that I never did it and when withdrawing from the casino I will put it in my wallet and will only sell on the exchange when I need it because usually the money from the casino will only be used to play again at that casino or a different one.
Would using an intermediary wallet to receive gambling funds be the solution?
Maybe this is a solution or you can use DEX if you intend to sell the results of your gambling.
