you won because you completed the task and kept floki currency in your wallet

Hello,
I just noticed that a cryptocurrency that I never bought appeared in my Binance wallet. After checking, this crypto is not even listed on Binance.

I would like to know if this could be an airdrop, an error or something else.
Has anyone ever had this kind of situation? What should I do in this case?

Thanks in advance for your clarifications!
