Running a casino is more profitable to the casino owners than to gamblers, and that's a known fact. If gamblers are allowed to win more than usual, that means that casinos will run out of funds to pay out. Since you are referring to casino coin, I have not really invested in any casino token, but I feel that if a casino is very successful and popular, that means their token will actually get promoted and will be profitable to those that invested in it. Although, as long as the token is still an alt coin, you cannot predict it.
