BTC isn't a belief at all because it is all based on facts. What BTC does is deliver serious actions due to its mechanics being based on the skin-in-the-game. The system makes everyone act towards a united goal not because all actors in the system believe in BTC, but because it is designed such that everyone acting towards a unified goal makes the most economic sense for everyone. You don't trust because you believe in BTC, you trust BTC because the system has proven to not be compromisable at all. If this had been otherwise, you would not invest in BTC and this is not because you lack a certain belief, but you are confronted with the fact that the system is not reliable.

Courage and patience are subjective attributes that have little to do with BTC itself. Many things involve courage and patience. BTC's price is partially reflected by belief, that's probably true for those who don't really understand the system, but decide to invest anyway. But at the end of the day the price is a reflection of its uninterrupted continuous reliability and validity.
