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.
A casino's own token is a good tool if it has a number of useful functions for the player himself.For example, I would be interested in receiving dividends or cashbacks. I remember a few years ago when there was a boom in casinos that created their own tokens on TRX, they were popular, but there were so many of them that they were practically no different from each other.
