I have to admit I was unfamiliar with Dan Olsen prior, but this singular herculean two-hour explanation of crypto is better than the entire HBO Max series "Generation Hustle" about grifters. If you had a sinking feeling that NFTs were a scam, this incredibly dense and darkly humorous look at NFTs ranks as easily the top things ever to appear on youtube.
I link this hoping to use my tiny bit of google index rankings in the hopes this becomes the default position on "crypto-bros". It's two hours, but I doubt there are many two hours of better YouTube.a
Also, some other YouTuber *who I think is a gaming channel?) gives an incredibly cogent explanation of the NFTs. There are a lot of really good analogies in plain speech.
