Does BTCC work in the USA?

I'm curious about the operational status of BTCC in the United States. I understand that they're a prominent player in the cryptocurrency space, but I'm unsure if they offer their services to customers located within the US. Could you clarify if BTCC operates within the US and, if so, what kind of services or products they provide to their American clients? Additionally, are there any regulatory hurdles or limitations that they might face in this market?
