The Vibe: Regular money issued by governments, like dollars or euros, that’s not backed by gold or anything physical—just trust in the government.
The Details: Fiat currency gets its value because the government says it does, and people agree to use it for taxes, debts, and everyday buying. Unlike crypto (which is decentralized), fiat is controlled by central banks that can print more anytime. In crypto, you often use fiat to buy your first coins on exchanges (fiat on-ramps), or convert back to fiat when cashing out profits.
Pro Tip: When starting in crypto, use stablecoins (pegged to fiat like USD) to park value without volatility. For taxes, track your fiat-to-crypto conversions carefully—most countries treat crypto gains as taxable when sold for fiat.
