Even Binance list a scam shitcoins that give huge loss. They just add a risk waning on every shitcoins that they list with high volatility and give the users the responsibility of due diligence.

I think this same scenario with MEXC since they just list a shitcoin which they don’t have control on what will be the outcome of the price since it depends on the traders who will buy and sell this shitcoins.

You have the responsibility to make a due diligence on what you are buying. Unless they freeze your account or any issue related to your exchange balance hold can be considered as scam by the exchange.
