Right, but now imagine you weren't one of the people who had someone knowledgeable and sceptical pointing out the flaws. Imagine all you ever came across was crypto bros and people who believed, repeated and amplified their bullshit. Imagine the received wisdom all around you, from your family, peers, role models, was: this is the thing to do.
Yeah, a bunch of people ignored you and ostracised you. But not everyone. Not most people. Most people never even got the chance to ignore you.
