Is BitMEX allowed in USA?

Hello there, I'm curious about the status of BitMEX in the United States. Could you please clarify whether BitMEX is allowed or not for citizens and residents of the USA? I've heard conflicting information and would appreciate a definitive answer from an expert in the field. Additionally, if BitMEX is not permitted, could you recommend any alternative cryptocurrency trading platforms that are compliant with US regulations? Thank you in advance for your help.
