Think about how many people exist on the planet that wish to own "perfect money" (with everything that represents). Now think about how many there will ever be on an infinite time scale. Is that number going to increase or be reduced?
Regardless of how many times it goes down in purchase power, the pressure for going up will always be bigger. Through time, there will always be more people that want better money for themselves, than the ones that don't (if that even exists).
The amount of #bitcoin you get, represents how certain you are of that truth.
