DAO.CASINO (BET) is a utility token so should have no problem getting listed on bittrex.
Will this coin ever be listed on bittrex or liqui?
The ICO was extremely successful and the team is very transparent. They update the community very frequently. They're probably working on exchange related topics. I don't see any reason preventing BET tokens from getting on the best exchange platforms.
