It seems MEXC is the best place to run away with the money

I don't completely understand what you mean with this sentence, but if you are trading shitcoins in any platform, you should understand that you can lose your money. Basically because it is shitcoins and not even about the platform per se.
I don't use MEXC although many coins getting pump and dump quickly. That is a scarry scheme for me to lose moeny.
Shitcoins get pumped and dumped all the time. That is the risk people take when they play with shitcoins and these coins are available on most centralized exchanges, not just Mexc.
Instead of Trust Wallet, I prefer to use Unstoppable wallet or HW for the best.
Good choice. Trust Wallet should not be used by anyone.
