I don’t consider Bitcoin to be a store of value. It’s a highly speculative asset. When I think store of value, I think things with a very long history of increasing value. That leaves the S&P 500 as the best place to store money, followed by owning your home, and then things like artwork or gold jewelry. Bitcoin is a bet on a new emerging asset class.
I think if Bitcoin already proven survived for many decades and everyone trust it, then Bitcoin can be said as store of value. Bitcoin would resistant against government centralization and dictatorship, but we don't know how much Bitcoin will worth since the adoption will highly decreased.
Fiat isn't a store of value too since it's only created by paper, but since everyone are trusting fiat and believe the value based on the number that written on the paper.
So we need to wait for that only to see if btc is really a store of value or not? I think that's boring but as of now, many people already trust bitcoin and can say that it's one of the store of value because of its limited supply and as we can see it grew a lot from its over 13 years of existence.
Btc adoption will not decrease but it can only increase since many people didn't knew btc yet. We don't know the exact value of btc but once massive adoption takes place then for sure its value can increase over 100k. Fiat money isn't a store of value not because it's only a paper but because its value depreciates over time due to its unlimited supply.
