I also prefer the casino to pay that fee, especially when Bitcoin withdrawals are made and there's a lot of congestion because prices go up at that point but most casinos have had a low fee that can be paid, another option is to charge a fee but allow an internal exchange where you can convert it to a stablecoin. This is important but since I like to play at a casino where I feel comfortable , what I look for first is that Once I'm comfortable, I think a fee can be paid without any problems.
