https://www.playbetr.com/There are many more but i can only vouch for these set because they are the sites that i come playing actively now so if there are casino that i can assure being legit , then those are the list .
Head straight to bustadice because throughout my gambling life butadiene is one of the sites that I have to withdraw high amounts on without any issues or requirements for withdrawal and there are also have bankroll features where you can invest your funds and share in the profits.
well Bustadice suddenly quit advertising here in bitcointalk, i don't know if they are still luring players from Inside.
