Just talked to customer support at MEXC and their exchange is no longer available to U.S. customers.

I was trying to reactivate an account that I had previously at the exchange. After several failed attempts to reset my password, I started chatting with a customer service rep who informed me that I was unable to reopen my account because I am based in the U.S. They also said that this is a new policy that just went into effect in the last day or two.

With Gate dot io already unavailable to U.S. users, it now looks like SushiSwap may be the last available exchange for transacting Moons if you are based in the U.S.
