Sometimes you may find unknown tokens of large amounts in your wallet. It would seem that this is happiness, but 99% of them are scams.
By trying to sell these tokens, you give permission for the contract to interact with your wallet funds. And such interaction usually has a negative impact on your wallet balance.
Very often the name of such tokens includes a site (domain most often .io) where you will be asked to sell them. Never interact with these sites.
If you still connected your wallet on a site you do not know or even signed a transaction, providing access to your wallet, all is not lost? You can cancel/verify issued permissions using special services, such as https://app.unrekt.net/. ???
