Why was Binance banned in the US?

Could you please elaborate on the reasons for Binance's ban in the United States? I'm particularly interested in understanding the legal and regulatory issues involved, as well as any specific actions or decisions that led to this outcome. Additionally, I'd like to know if there are any ongoing legal challenges or potential reversal of this ban in the future. Finally, what impact do you believe this ban will have on the cryptocurrency industry and Binance's global operations?
