So far so good. It's a positive thing that you agree that banning a player and taking his fairly won coins isn't the way to go. Your casino also means you get to make the rules about who is allowed to play there and who isn't. Limitations are generally not welcome as they send the wrong signals and saying we don't appreciate successful gamblers who win. But like I said, that's your choice, and if the players don't like it, they can take their business elsewhere. I have a good feeling that this will end well.
