Nah, not a pyramid scheme. The money I've made isn't predicated on recruiting a downline in any way. NFTs are closer to a luxury goods market. Lot of sneakerheads love this stuff and it's not hard to see why when you get into it.
I think crypto in general is pretty dumb. I owned bitcoin back in 2012 and thought it was stupid, sold for a small profit back then. Had zero interest in any of it until utility came. Decentralization is a fantastic concept though, and it's shame that it's libertarians who are the ones into it and creating the world we're going to live in here.
A lot of the commentary on Twitter and so on is really bad. I've seen tweets with 5-6 figure likes where the person is being trolled completely by a crypto person (think person pretending to be upset that someone has right clicked and saved their NFT and everyone actually takes that bait) and nobody realizes it.
The environment thing won't be an issue shortly. There are already zero emission blockchains.
