I think Binance requirements already change since then which is the reason few casino tokens listed there. I think only Fun tokens is currently listed on Binance.
Betfury has had a Curacao license for a long time now. Isn't this enough for listing, or does Binance require some kind of special licenses from gambling projects? By the way, I have a strange hypothesis. What if major exchanges(Binance and others) ask for some personal information about the developers and project management, which the Betfury team simply doesn't plan to provide since they want to remain anonymous, especially their CEO?
