Fiat Currency Beginner
Fiat is government-issued money — like the pound, dollar or euro — that is not backed by a physical commodity.
Crypto prices are usually quoted against fiat, stablecoins are typically pegged to it, and "on-ramps" and "off-ramps" are the ways you move between fiat and crypto.
This definition is educational and not financial advice. Crypto is volatile and high-risk — always do your own research.
