Binance has listed some projects without even knowing their investors right after their private sale, and these companies weren't trying to rise too much during their sale. White papers were just next level and so were the devs so they were taken seriously.
I just saw a recent tweet from Mithril Project that they are asking CZ to return their 200K BNB deposit as requirements for their token listing after their token recent delist. Im positive this info is part of there NDA which Mithril already break since there partnership is already over so theres no way for them to lie about this info. Binance is really charging a huge fee in the form of buying huge amount of BNB (by that time was 8$ per BNB).
