In more detail
Fiat is ordinary state-issued money (rubles, dollars, euros), and the «crypto ↔ fiat» direction is the most common in exchange. Fiat deposits and withdrawals go through cards, SBP or cash, each with its own limits, fees and risks (e.g., chargebacks). Stablecoins often serve as a bridge between crypto and fiat.
