You can't sell it directly. you have to mine minereum from there site but it requires lots of fund. I will suggest you to leave minereum coin as it is please don't invest in this project it seems like a very big scam...
Minereum is a project trap from scammers who want to take everyone's money because when everyone starts sending it to the exchange only the gas costs are deducted, while the coins will remain in their respective wallets.
