If you operate your casino without license as it might be in terms of cryptos where the government can't track the transactions to imply you to get licensed but you would not get much response for such a casino. People needs to be secured about the games they play and hence each gambler including me would choose a platform which is licensed and probably fair.

You can consult your CA to get some more legal information about launching a casino in your region. You would also need to set-up a office space where you could store the credentials and you could run the platform from that place. You would need to be centralized if you wish to get licensed and for it you would need to show each and every transaction/bet to the authorized parties in order to get you a license.
