In as much as I don't I don't gamble in the non licenced casinos, I won't even tell it to what region that may accept it because me as a reputable player, I'd always want that convenience and reliable casinos with good reputations to play with because that's literally where the trust begins between the house edge and the players.
I'll also let you know this that there're risks involved in Investing on non licenced casinos which are government coming against you at any given time with a change of mind to dismiss non license casinos and also, players are mostly looked at the casinos registeral or license permission before playing on your site.
If you don't put this to considerations, then you might end up wasting your funds because no one would want to play with you and the government after you in the future will be a double lost of charges for you.
My advice is that you should stay warmed unexecuted to the casino until you're ready to acquire a licence.
