Personally, I don't believe in casino coins, because 95% of the users sell them immediately after receiving them....at least that is what I think they do.
Most of those tokens are based on utility bases and for that their may not be Build to make significant profits for their holder's and just in the interest of the casino system such coins shouldn't be taken seriously as an investment tool, I will rather choose other coins instead of casino tokens if I am looking for profits instead of utility.
Yes when casino sites launch a token they are definitely utility. Because they can be used to gamble. and since these tokens are utility, if that casino platform is very popular, then that token has a good value. But if that casino site is not very popular then investors are not available for the tokens. this is what Rollbit is for freebitco casino being the top casino, their tokens RLB and FUN are well positioned in the market and BFG failing its value day by day also also investors avoiding that
