The casino token has limited use case if any since I can only see its for staking and getting revenue from the casino's profit. Nothing else was said for its use case though it can be used to bet on the casino. With that, the supply can really reduced until the casino owns them all.
With limited use, no token can do anything big in the market. Trying to attract investors with staking is a very poor effort. No investor will invest real money in a dumping token just to get a fixed % interest. So in order to create real demand, every project should create the maximum ecosystem for the use of that token on gambling websites.
