While both types of currency serve as a medium of exchange, store of value, and unit of account, there are significant differences between the two:
Given that the primary objective of cryptocurrencies is to act as a form of money, there is a close relationship between 'fiat' and 'crypto'. Most cryptocurrencies are primarily traded against fiat currencies in crypto exchanges. This is often displayed in the form of trading pairs (e.g. BTC/USD, ETH/EUR) on various cryptocurrency trading platforms.
For someone to acquire cryptocurrencies (unless they're being paid in it), they typically need to use fiat currency to buy it. Many cryptocurrency exchanges provide a service of trading fiat money into cryptocurrencies and vice-versa. The prices are determined based on supply and demand mechanics in the market.
Understanding the term 'fiat' and its relationship with cryptocurrencies is fundamental for anyone exploring the world of digital currencies. It will not only help in understanding the economics behind these currencies but also in making informed crypto trading decisions.
