"Logically, would it be possible for people to exchange $ 300 for 12k Euro?"
Why $300 for 12K Euro?
I say that I'll pay the person $300 who will help me to cash out MNE to BTC or any other useful altcoin which I can easily trade.
At the moment I am able to withdraw 32k MNE just need to pay eth fees of $44. I ask here because trustwallet.com It's a trusted website.
You cannot cash out. It's just a waste of energy getting it. All active wallets have MNE tokens. Visit their site, and read more details about the conditions for getting one. This has nothing to do with Trust Wallet. Because Trust Wallet is using an Ethereum wallet, Trust Wallet also contains MNE tokens.
