There's no need to think about useless coins like MNE, because your time will be wasted if you try to care for it,
so it's better to ignore it than to care without any benefits that you will get from it.
Yes it is a waste of time. There are lots of people who receive the same amount of minereum. I don't think it's an erc20 token but in smartchain as mentioned in my previous post. Just don't do anything that involves minereum in the address you own. If you are not sure then don't ever use that wallet. There are other tokens that is the same as this one like vera.
