I believe there actually has been evidence of this going on in this brilliant NFT scheme -- which, by the way, is simply a lesson lifted straight out of the elite rich's world of "how to launder money using art". In this instance, an artist is commissioned a painting by said rich guy. But instead of paying the artist, said rich guy instead agrees that he will bid for and pay a ridiculous amount of money for it, using the services of auction house to promote and legitimise the deal.
Artist keeps promised share, auction house keeps promised portions and, if lucky enough, rich guy actually gets outbid by some other dumb rich guy -- bidder keeps profits. Clean.
In NFT, replace rich guy with NFT minter, replace auction house with NFT marketplace, and remove need for actual artist (you've got AI tools now minting NFTs on script).
P.S. Ought to look also into stablecoins and "defi" for more cyber laundering loveliness.
This has been established long time ago. We do not know "all" people who does this, but we have caught a lot of people who did, the accounts were tracked back and eventually shown that they were connected to each other. Which meant that the same person who created the NFT, was the same person who bought it for silly amounts as well.
This means that people overprice their own shitty stuff and then take advantage of the situation by selling it to others for cheaper if they have to. Do not consider just those 60 million type of stuff, people do this with even 200 bucks worth of stuff, this is why it is quite important to check the projects and see if they are legit or not.
