Casino tokens aren't that bad but I think the casinos are not able to provide value to their tokens and that is the reason we do not see any interest and hype for the casino tokens. The casino should give special incentives to the gamblers who gamble with their token and this will increase the demand for those tokens.
Even a more aggressive approach can be to compensate the users some percentage of the loss in the form of the token, buyback plans and staking should also be implemented and all such things which make people buy the tokens and increase the demand.
Some of the things you mentioned have been implemented by the casino whose signature I currently use, but it seems difficult to compete with other tokens that are not casino-based, but if the staking feature or others are not implemented, BFG may not last.
Casino tokens are less noticed, maybe because this token is not like a new token that can provide quick profits because of the pump scheme, also because there are not as many crypto casino users as imagined or when compared to traders.
But does this casino also have its own token? If so, focusing on being listed on a big cex could boost the price, but impressive development could make this token even more famous.
