I would have posted this here:
https://bitcointalk.org/index.php?topic=5599137.msg67320437#msg67320437But I think it is a very important information that should be shared separately. Do not just send coins from MEXC to another exchange. Either you should not send it or investigate that the exchange accepted transactions from and to MEXC.
You know what happened already.
Binance has stopped its users to send coins to and from MEXC. Maybe other exchanges might join soon.

I am locking this topic for you to continue discussing it on the other thread.
