Isn't that the risk of hacking our personal wallets, and of course as gamblers we will avoid problems like this unless we use another wallet or spare wallet that is only used for gambling.
I personally still prefer casinos with deposit and withdrawal features because it makes it easier to organize or manage finances, besides that using deposit and withdrawal methods has become habit.
Maybe some gamblers will be happy with feature that connects their personal wallet directly to the gambling site, but I sure they will only use another wallet, not their main wallet, serious problems will be felt if problems occur when using the main wallet.
No matter how good the casino use, if it has direct feature for connecting personal wallet, still have to be careful.
