> The premise given is that some other technology will displace Bitcoin. This is not implausible, but it also applies to fiat! Fiat is backed by the/a government. The main scenario that I can think of in which something replaces fiat currency is if something replaces government. If an event occurs in which government is no longer around, there will probably be bigger problems to worry about, e.g., when the Imperial ruble was replaced by the Soviet ruble (and then the Russian ruble): * https://en.wikipedia.org/wiki/Ruble https://en.wikipedia.org/wiki/Ruble * https://en.wikipedia.org/wiki/Russian_ruble https://en.wikipedia.org/wiki/Russian_ruble
