Bitcoin has no intrinsic value.
What intrinsic value did a bunch of servers running a page-ranking algorithm and a plain webpage with a single input had until it started to be used by people. The value of bitcoin is its network effect, being permissionless and unmatched record. That is not something you can simply recreate.
Its price is a narrative.
That is your personal opinion if you buy or bought any crypto because of the narrative. Many people want to pump it because of the narrative and many people fall for it. Yet, these are exactly the kind of people who we don't find here when bitcoin is at 4K.
At infinite price, we'll spend all energy on mining Bitcoin. It doesn't sound like a good world to live in.
What "model" are you referring to that says that bitcoin will have "infinite" price? Or that the world will spend all the energy on mining? Is that just conjecture or you are talking based on study and sources?
