The best "cure" to the problem is to educate people that buying this crap is a waste of money and a con. That would eliminate the incentive to create it in the first place.
There is no way that the
"cure" will work, not today. When too many people see how the images of pixelated dumb apes are getting sold for millions of dollars, how dumb pepe memecoin gets a huge market capitalization, how out of nowhere dead meme coin overnight turns into a coin with a huge market capitalization, it's hard to make people believe that this crap is a waste of money when potentially it's possible to make tons of money out of thin air.
If gullible people wouldn't fall for scams, there wouldn't be any scammers left.
I think tat NFTs, Memecoins and similar nonsense piece of arts are the place where most of the money gets laundered.
