> It wasn't just that crypto was an obvious grift

Was it universally obvious? Hindaight is 20/20 There were many block-chain startups funded, and even FAANG got caught up in the hype. FWIW, I was a crypto sceptic, but I had many arguments with believers online and in my social circles. Side note: a crypto enthusiast colleague bought a house off their crypto gains, it may be a grift, but a small number of crypto-believwrs got really wealthy, and you're not going to convince them.
