It reads like a concise summary of red flags around cryptocurrency, on many dimensions. It doesn't mention 'tendies' at all, call anyone names, it doesn't reek of someone bitter because they lost all their money or missed out on a get rich quick opportunity, or have that cynical nihilistic "I'm smarter than everyone" geek attitude. And it isn't framed at a rant against a /group/ as much as a warning about being a victim to the (most vocal) self-appointed leaders of the group.
Yes, they're not citations to academic studies, but you don't see an in-group/out-group dynamic of "people who believe in the glorious future of Canadian dollars" vs "people who don't", or the desperation for the world to realise the truth of Mexican Pesos that only the faithful currently know, or etc.
