In the end, it's a bunch of crypto bros who want to show how much they don't depend on the government suddenly realizing that FDIC-insured accounts were actually developed for a reason. It's people calling dibs on numbers. And yeah - the blockchain has led to all sorts of interesting ideas, but the money you pump into the currency du jour isn't really worth anything once people move on to a new trend, or once your exchange is hacked, or whatever.
I've been getting told for months that I'm missing the train and making a bad decision by a guy who bought BTC at 60k and told me "everyone" was saying it was going to go past 100k. And apparently I was a fool for investing in property and a diversified stock and bond portfolio. So yeah - I feel somewhat vindicated right now.
