This is a really good question. Maybe their treasury is not doing well and they can't afford to list (which would be understandable on these markets). Then again gambling related crypto casinos works sort of seperate to markets as at least bfg tokens have actual utility.

But why bother listing to shady cex? Maybe they promised a "top" centralized exchange and fear lawsuits from whales that have invested lots of money in bfg. Those could happen and it's a lower risk just to list to any top exchange (even if they are mostly faking volume) then endanger their company.
