MEXC (non-KYC exchange) is apparently no longer providing services to the USA

Their homepage has a warning in red text at the top of you load the page from a ISA-based IP address. The text reads as follows:

"Your IP and nationality indicate that you are located in a country/region where MEXC services are restricted. According to MEXC's terms of service, MEXC does not provide services to users in the country/region where you are located. If you have any questions, kindly contact MEXC Customer Service."

To my knowledge this was not previously announced. I am told you can withdraw funds from there but haven't confirmed with anyone if you can buy or sell still. Probably wise to withdraw anything you had held on there, though in general, storing crypto on a CEX is risky anyway.

I'm guessing this is because it's a non-KYC exchange.
