This comment applies if you think that art itself is a scam, or that art needs to have "use" outside of perceived financial, social & aesthetic value.
HN does tend to be especially bitter towards Crypto, something that I think will fade with time as it blends into culture without seeming like some "charlatan intruder from elsewhere".
I tend to think the rise of NFT markets represents an inflection point that will only be obvious when we connect the dots looking backwards. Plenty of people reviled Duchamp.
P.s. Please let me know where I can purchase an Alpha-Centauri real-estate NFT
