Huh, that is weird, because he doesn't have any referral link or anything, and MEXC is (as far as I know) a legitimate exchange, not some fly-by-night thing.  They've been around for a while and I haven't seen many complaints about them on the forum.  Damn newbies, ya know?

And I guess I missed this thread when it was started, but what I'll tell OP is that Coinbase did exactly what they did to him back in 2015/16 (can't remember exactly when).  It was because of a stupid error I made with a checking account I had linked that I closed but never unlinked from Coinbase.  They didn't contact me, didn't try to figure out a way to keep me as a customer, just closed my account. 

I can't stand them, even if they are one of the most legitimate exchanges out there.
