"The Wash Trader"

This is a manipulative character who often works alone or is hired by rogue developers. They create two accounts (Account A and Account B). Their activity? Account A sells an NFT/Token to Account B at a high price, then Account B sells it back to Account A. The goal is to create the illusion of fake "Transaction Volume" to make the project look busy and popular in the eyes of the public, thus luring genuine (retail) investors into the trap.
