What is the rich quack on Binance?

Excuse me, could you please clarify what exactly you mean by "the rich quack on Binance"? I'm not familiar with that particular term or phrase in the context of Binance, which is a popular cryptocurrency exchange. Are you referring to a specific user, a meme, or some kind of inside joke within the Binance community? If you could provide a bit more context or background information, I might be able to give you a more accurate answer.
