Yep, As of now there are a very limited use of casino tokens but maybe soon they will add new utilities to it for it to be alluring and more effective to the market. On the early phase of Binance token BNB, They also have a limited utilities. As far as I remember, Binance is doing hard core promotions on their token BNB. They are offering trading fee discount if you use BNB on their futures trade. I don't know if they are still doing it but I remember that they are promoting it hard and the utility of BNB that time is not that much compared what we have today. There could be few utilities for casino token like using it to be a VIP on a casino, have a priority customer support or having an exclusive promotion to those who have the casino coin. We don't know yet but I believe that it would be hard for those casino to implement things right.
Difference being that BNB token (which was erc20 at the start) had a whitepaper with specific plans for the future the start. They didn't invent them as they go. It wasn't going to be just an exchange token but a coin with its own blockchain. While BFG still has no specific future plans that i can see. Even the roadmap has ended. Yeah there could be some gimmicks they could implement into it but so far they haven't really confirmed any specific plans.
I mean it's ok to dream and shill for the token you are holding but BNB and BFG were never comparable even in the terms you describe. Binance had a doxxed CEO from the start. BFG has chosen whole other way.
