Hi Weilii, thanks for stopping by to read my article!
The OED definition of fiat currency is: Inconvertible paper money made legal tender by a government decree.
So to address your first comment: 99% of all crypto is not fiat.
Yes most cryptocurrencies are not convertible into a bar of gold or silver, but they have the option to be backed by assets. To address your second comment: At no point did I say Bitcoin is a stable currency which could replace money; in fact I suggested quite the opposite.
The article discusses whether localised community cryptocurrencies could work as money in the future. And it is of my personal opinion that people should have the freedom of choice.
Your government chooses not to back their currency with physical assets... with blockchain technology you can choose what type of currency you wish to use as an individual and what it's backed by. Thanks for reading :)
