I have received some unknown ERC20 tokens in my metamask wallet and I am pretty sure I have not participated in an airdrop or been promised to receive it from any ofother sources.
I have this token in my Ethereum address, I also have this in my Binance address, and now on Polygon but I don't mind it at all, I long know this when Minerium was airdropping this shitcoin, I wonder why you receive it when you did not participated in, I once participated using two address in Ethereum, and I have it in my Binance chain and Polygon chain with the same address, so if you participate in Ethereum airdrop you'll also get it in Binance and Polygon chain with the same address, I regret participating in this airdrop.
Just ignore it don't spend a fee just to get rid of it.
