I mean, shouldn't it be taken as a lesson that if the kids want to play with fire, an unregulated market (include MLM-Ponzi scheme structure by all accounts), then that's one type of pitfall that exists?

Elon's also publicly said, tweeted not too long ago: "Bitcoin is almost as much bs as fiat money" - so just because the markets didn't know or report on that to help provide a balanced, critical breakdown to promote balanced news - that's all Elon's fault? The mob of irrational buyers have no responsibility to know what they're "investing" in or to research and understand statements or behaviours about what they're "investing" in?
