Would you say the same thing about Bitcoin? Will that house of cards all fall in the next crisis/downturn/depression?

I personally think Bitcoin will eventually peter out, and that it's fairly risky as it has definitely been pushed by vibes and promotion and everyone wanting to get in on it

I mean that can apply to anything. There's nothing intrinsic about gold that makes it valuable other than it's rare, but there's plenty of things that are relatively rare that aren't valuable. Yes there's industrial uses of gold but that's not why we as a society and a species treat it as valuable

Maybe bitcoin is the new gold and will hold value forever, and as more serious people get into it, it will lose its volatility and be less subject to the vibes shifting and there being a run on the market. Maybe not

It is different from Elong stocks, though, because the myth of Satoshi aside, it's not exactly a cult of personality like his companies are

Hasn’t it crashed in every economic downturn and financial panic so far?

To me the difference is that BTC's continued value isn't predicated on the actions of one person, who has continually proven himself to be childish, mercurial, and dishonest.
