Success of some altcoins don't entirely depend on the whether the company that built the token is generating money or not, it still very much depends on the type of community the project manages to build, and also another important factor is in the area of use-case, aside buying and selling the tokens, what other interesting things can investors decide to do with their token if they wanna spend it, but don't wanna sell it? this is how most tokens gain good value in the market, it doesn't entirely depend on whether the company is generating income or not, for all i care, a company can be generating income and that income being generated wont have any positive effect on the tokens performance in the open market, this simply means the managers of the company are just enriching themselves, and careless about the performance of the token in the market.
It still matter on their money generated on their platform since for that they have a lot of money to use to create more use case of their token, also maybe they can use that for multiple marketing together with big exchange listing. Those factors are important to hype their followers and if they don't have enough money to support their project and let the staking feature only the use case maybe investors will get bored and leave the thoughts of acquiring this.
You are both correct. Most altcoins doesn't even want to "generate money". If their tokenomics have working game theory (tx system or something else), they could raise in value as a side effect by design. But most of them are not bringing dividends as that would immediately make them securities by the standards of howey test.
Value and future of BFG however solely depends on the casino income. It isn't like most of altcoins (or tokens, if we want to be specific).
