I, as an user, prefer to gamble on a casino that pays my withdrawal fees because I feel like I'm treated better.
There's no one in this world want to spend more than what it should be except they're an idiot.
I kept thinking if there is any casino that pays every users withdrawal fee, I doubt there should be any available in the market. What exactly is the point of doing business and getting more profit for site maintenance and others if withdrawal fee can't be a priority, it's not ethical at all except it should be a promo for newly registered account to allow withdrawals without fee on the first three times.
