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.
General cryptocurrency enthusiasts are not gamblers, very minority of them are gamblers and degens. With altcoin enthusiasts and investors, it's their big mistake to ignore gambling casino tokens that actually have good companies and foundations behind. They are more easily to invest money into altcoins that are not backed by any solid company, and they simply buying promises and futures of those tokens.
Gambling tokens from successful casinos are better, even they are less noticable in cryptocurrency communities and altcoin investor communities.
For so many altcoin exist on the market for sure that it will be hard to choose on which of these are good for their portfolio's that's why its important that the casino tokens should have good marketing campaign so that they get an exposure to people who usually invest on altcoins and their scope is not only limited for gamblers. I don't think its a big mistake but still they could do something so that they will not missed out any possible good development for those casino tokens out there.
For now we maybe didn't see those good result from these tokens. But if they are consistent and always do good towards helping their token to bring some good development also some exposure then we can provably say that there's huge chance for those tokens to pump in future.
