Bitcoin "the system" doesn't require faith to work. It works by pure cryptographic rigor that is provably infeasible to cheat, along with an adaptive ruleset that responds to changes in external conditions to keep running as designed. It just works, and I don't need any faith to know that. I just need a solid understanding of math and computer science.

Bitcoin "the price" is fundamentally different from the system, and really just serves to operate as a signal for how much collective human attention and trust it is gathering. It's incredibly volatile because it's still so young and finding it's place.

I also don't think the religious element of bitcoin is likely to be a long term thing, but a kind of bootstrapping mechanism to both draw attention, and nurture a core foundation of devotees who are committed to working diligently to integrate "the system" more and more into the real world.
