Yeah other than staking/farming and betting, they have not added new utility to the token that actually matters to bettors (yet).
What else would you want to add ? The cashback is based on VIP level (like it should be) and all bets that you play with the BFG token are also taken into account to level up.
An example would be increasing user
XP on leveling up when betting with their native token compared to other cryptocurrencies that's based on USD value of bets. Again, that's just an example and they can think of something creative that would bring new interest to the use of BFG.
Have you ask their live support regarding this? I'm Surprised the forum representative have not responded to this yet. I'm guessing the limitation is related to your Betfury rank.
