Bitcoin will never depreciate but the fiat system will due to the inflation.
The only rule of bitcoin in this market is just an alternative if we think of using it as online currency but a potential investment as adoption is expected while supply will eventually reduce over time.
people would realize that trusting the banking system is wrong as it's controlled by the government, there is no transparency even the suppose transparent which we called a business of trust, only decentralized asset is transparent and that is bitcoin.
I would say you shouldn't trust banks because of the fractional reserve, and you could say its the banks that control the gov not the other way around.
But how hard it is to tell people to find the truth about fractional reserve? And how would the world economy collapse the moment people discover it? This is because the mantra of the chicago school of economy would collapse (as it appears to be collapsing right now).
You think inflation is you major problem? But most of the money in "circulation" does not exist anywhere. Yes they print and reduce interest so people get in debt, they are afraid people are not getting enough in debt, this is the weakness of their school (growth by debt).
Bitcoin as money that does not lose value overtime, stimulates savings rather than spending, this clashes against Chicago school dogma, and can only be comprehended by studying the Austrian school of economy (growth by savings).
Bubbles are literally caused by this system. Once people get off that train, bubbles disappear entirely, forever. The Austrians advocated a solid money, something like gold, but not something backed in gold, i had to be gold itself so that you did not have to trust anyone to fulfill a promise. But now we have Bitcoin, and this trustless coin can fill that need perfectly without the risks of handling actual precious metals.
Little by little, people will learn the truth. Of course fiat is going down, its been intentionally made to go down by governments, and the recurrent crisis can only push it down a bit faster than "anticipated". Remember, even if if loses value faster and recovers, they will never allow it to go negative (deflation) because their Chicago school dogma forces them not to.
Under Chicago school, deflation is taboo. Under Austrian school, it is most welcome. Bitcoin is the future, fiat is the past.
