Yes, that's right, bro, such coins are intentionally sent by scammers, especially after you make a transaction ,it doesn't take long fake token suddenly appear in your wallet. and need to remember?
1. Don't try to exchange coins like that. if you do swap then you will only lose money with such transaction fees.
2. Such coins are just a kind of damn bot, you can buy them but you can't resell them.
actually not only happening on the BSC network, but in several other blockchains such as Polygon, Hecoscan.
my advice, just ignore it.
