Even fiat currency has intrinsic value. The Zimbabwe bills that were inflated to hell and beyond, then replaced, which aren't even legal tender any more, still have value as collectible notes. You see them on eBay all the time for a buck or two.
Nobody will pay anything for your Bitcoin wallet if Bitcoin fundamentally fails, just as nobody will pay for your World of Warcraft gold when the pull the plug on the last WoW server a decade or two from now. It's just a bunch of useless numbers.
If you're "investing" in crypto, that is speculating, then fine. If you're thinking it's a safe and secure way to store money you're mistaken.

Because Bitcoin was literally created to imitate gold, with the idea being to propagate crank goldbug conspiracy theory economics.
This is why the price is so volatile - as an imitation of the gold standard, bitcoin wants to be money but actually works like a commodity, with booms, busts and bubbles.
I understand it - even the term "gold rush" could be applied here, where people the get the fever and sometimes do irrational stuff to try to strike the good ol'gold nugget.
You can learn a lot from the psychology and sociology side of the Gold Rush event, and surely you can compare it to the crypto event (after all, that's what history is for).
But like you've said, Bitcoin was created to imitate gold... still it's not gold.
I don't get why crypto keeps being compared to a metal.
