Recently I wanted to sell a token at a good price but I didn't manage it. However, someone else who has an ethereum address and is not a bot warned me.

The strange thing is that in the tab tokens I do not have a single transfer.

Only in the transactions tab are swaps and quite often. How is it and why does it work like this. For the first time I noticed something like this.

The guy sells tokens and maybe I buy them but I only see swaps, you can not see that he owns tokens at all. Can someone explain what it is and how it works?
