Why Bitcoin It is important to understand that Bitcoin was originally designed purposefully to combat the inflationary tendencies of governments and Central Banking Systems. When economic downturns occur, governments are always tempted to print more cash, saying they are "satisfying demand for cash."" In reality, they are debasing the value of cash for all who hold it and reallocating value to whoever the government pays with that newly printed cash.
From Satoshi Nakamoto's thread unveiling the Bitcoin white paper:
The root problem with conventional currency is all the trust that's required to make it work. The central bank must be trusted not to debase the currency, but the history of fiat currencies is full of breaches of that trust.
Bitcoin is more typical of a precious metal. Instead of the supply changing to keep the value the same, the supply is predetermined and the value changes.
This is why bitcoin has come to be known as digital gold. Bitcoin provides the same protections for savers that gold provided in past inflationary periods, with vastly improved accessibility and portability. This is due to bitcoin’s supply not responding whatsoever to changes in demand. Precious metals are the only other assets on Earth with a total supply that acts similarly, though not as predictably, as bitcoin.
When governments decide to spin up the printing presses for their fiat currencies, store-of-value assets like Bitcoin and gold serve as exits from fiat debasement.
