All MNE holder can do nothing, the developer has stopped to develope this coin and now become garbage.
MNE coin are usually given away for free by the maker. and I don't understand the purpose of them sending this token. which obviously costs gas for them to be able to send it across multiple wallets. if this coin has a telegram channel, please ask there about this coin, if it has a telegram channel, then just let this coin fill your wallet
This giveaway or airdrop done years ago when gass fee not high like today, and if I'm not wrong this coin just for staking purpose I mean holder get interest from holding it.
