NFT's feel like you've got four types of people.
1)Wealthy investors speculating and legit trying to play it like a market (as legit as you can be in this capitalist hellhole)
2)Tech bros with too much money in their hands
3)Money launders selling and buying these items back and forth to avoid the feds, probably sitting at home in their t-shirts surrounded by bales of packaged coke
You can't have a cert of authenticity...without an actual group to regulate and monitor said certificate. Who's going to deal with copyright etc...
