This is a good read on why BTC and others still have value.

An important and valid counterpoint is that cryptocurrency wealth is just as centralized and we are merely trading the old selectorate of money for a new, but no more inclusive selectorate.

There is good evidence for this. Estimates suggest that as few as one thousand people own 40% of Bitcoin. That’s not a wildly different number then what the current system looks like.

In this view, the “bitcoin revolution” is like most of the revolutions preceding it where we simply traded our old overlords for new overlords.

The open-source, forkable nature of cryptocurrency give me hope that this will not be the outcome.

Historically, it was possible to use different currencies for different purposes. While you may have been required to use a certain national currency to pay taxes, you might use a locally issued bank note for the purpose of trading in your village and you might use specie (gold and silver) to store value in a way that could not be debased if the King got into too much debt. In other words, there was a competitive market for currency for most of its history.

It was only in the late 18th century that this competitive market collapsed these into a single currency backed by national governments which outlawed other currencies to make it easier to levy taxes.

Because of their open-source, forable nature, cryptocurrencies bring back the possibility of different currencies being used for different use cases and force currencies to compete for users. The monetary selectorate can make its opinion known by buying, selling, hoarding or dumping various coins as they see fit.
