That is a strength of crypto, rather than a weakness. Look up the primary properties that money needs to have, and you'll see that crypto checks all boxes.You can make things with gold. That's where it's worth comes from, not as a "store of value". So while it's worth in essence is manipulated by speculative market forces, it will always have some worth. Crypto has no worth other than due to speculative forces.
That applies to every market. If everyone decided to cash out their Amazon stock all at once, its worth will also plummet. Realistically, this is not going to happen for neither Amazon nor Bitcoin (among a few others).If everyone holding crypto decided to cash out all at once, it's worth would plummet to zero so fast that half the speculators would get nothing.
That is even more true for your savings in your bank account, and even more so for your pension/retirement money.Holding crypto is like playing high stakes poker.
There are more than a handful of "crypto players with brains" as you call them, that are simply accumulating. You might know a few, like, Michael Saylor, Elon Musk...Every crypto player with any brains is simply calculating when to exit the market with the most fiat currency they can. It's a game of financial chicken... nothing more.
