I think that bitcoin was created to kill the dollar, even though it could take 100 to 200 years to play out.
Bitcoin is the most sound money every in existence, but bitcoin would not be able to transition the whole of the world's finances in a short period of time, especially since it has take nearly 15 years to go from zero to perhaps somewhere around 1% of the world's population invested into it... or having some level of exposure that might be even considered as low coiners for some of them.
Both systems have to exist in parallel, and sure there is not exactly a dollar system, even though the dollar is the most dominant of the fiats, so there are a lot of fiats, a lot of shitcoins and a lot of places that value is inefficiently stored, and bitcoin is going to eat the lunch of those various less efficient value storage locations (whether we are talking about fiats, or gold or properties or equities or the other various places that value is being stored) and bitcoin will serve as both a place to store value and a place to transact value, yet in the meantime, why are we going to spend our bitcoin when there are less efficient fiats (and other kinds of value) that we can spend first?
- I think it's going to happen sooner or later. If not Bitcoin, some other currency will eventually replace the dollar. As history has shown, whether it's dynasties or currencies, they all go through four phases: "Creation - Establishment - Decline - Collapse," and this cycle typically lasts about a century. Currencies are a bit different; they won't disappear entirely, but they can certainly weaken. We've seen this before with the British pound dominating the world before the rise of the dollar.
- Why do I believe the USD will weaken soon? It's because of the current global situation and the declining power of the United States. People are gradually realizing that the dollar they hold is losing value due to inflation and the Federal Reserve's extensive money printing.
- In contrast, Bitcoin is proving its superiority as it remains beyond the control of any government. You can see a Bitcoin - Gold - Fiat currency comparison in Fidelity's research paper below.
