I created a list of casino that gives dividends to their token holders as you can find here
https://bitcointalk.org/index.php?topic=5353217.0 Sorry in advance as I have not updated for a while, but you can check it as your references or you may give some more information about the casinos with similar feature that are not on the list yet.
I recommend that you update it for OWLDAO and for those who want to to know CRYPTO CASINOS WITH STAKING FEATURE and token with staking feature you made it right by having BFG token is on the first rank they deserve to be in that rank, Funtoken maybe old gaming based token but BFG token leads the pact when it comes to innovation in the casino based token, I hope there will be more token-based casino the gambling industry is one the leading industry in the Cryptocurrency.
