theres a dimension where an NFT "appreciates" in value and sold at a premium or offset than what was it was originally acquired at.

theres also the uncaptured exchanging of hands between bidders overpaying to build an asset bubble.

I think its better researched replacing NFT with "Fine Art" and seeing how money laundering in the art world happens [1]
