NFTs are, and will remain, primarily a marketplace to launder money; Just like the "high art" scene before it, but with crypto-bucks. Sure, average piss-ant millionaires can pull their publicity stunts and grifts, but that does nothing but draw the spotlight away from the billionaires running their $$ through the wash.
Launderee: I sure would like to use this blood money, but I don't want the tax-man getting wise
Launderer: Have you considered "investing" into NFTs? My friend will sell you this beautiful image of pregnant Sonic for $3 million in crypto
Launderee: Why would I do that? Sonic doesn't even have that great of tits
Launderer: Because, good sir, then I could purchase it from you for $2.5 million in clean cash. Boom. Money washed, minus my fee of course.
Launderee: Okay, but I'm screenshotting that sweet sonic pic.
The end.
