If you don't know where a token comes from that is suddenly appearing on your wallet then i would advice you to never interact at all with that token. Don't send it anywhere, don't stake it, don't do anything. I have seen reports of people that somehow lost control over their wallets once they interacted with suspicious tokens like Minereum for example, if that is true and technically even possible, i don't know but it is definitely wise not to take the risk to try it out. I also have Minereum on my BSC-wallet, but not on my ERC-20 wallet, which makes sense as the transaction fees of BSC and Polygon are so low that the scammers can afford to just sent their coins to almost everyone.
