Bitcoin will resist inflation and is somewhat out of control of governments or any central authority. People in countries where the govt has screwed up the currency can use it to get money out of the country or as a stable store even if dollars or other physical currency is in scarce supply. My family fled china carrying their wealth as gold and bank checks. Today, people can transfer their wealth as bitcoin across international borders.
The fundamental properties of money are:
<<Fungibility: its individual units must be capable of mutual substitution (i.e., interchangeability). Durability: able to withstand repeated use. Portability: easily carried and transported. Cognizability: its value must be easily identified. Stability of value: its value should not fluctuate.>>
It is not unreasonable to argue that fiat currencies around the world are not stable because of inflationary monetary policies. Buffet always holds billions in cash which is constantly depreciating in value.
