Exchanges are your gateway to buying and selling crypto. Learn the differences between centralized and decentralized platforms, what fees to expect, and how to pick the one that fits your needs.
A crypto exchange is a platform where you can buy, sell, or trade cryptocurrencies for other digital assets or traditional fiat money (like USD or EUR). Think of it as the crypto equivalent of a stock exchange – but with important differences in how they operate and who controls your funds.
Exchanges fall into two main categories: centralized (CEX) and decentralized (DEX). Each has its own trade‑offs in security, convenience, and control.
Examples: Coinbase, Binance, Kraken.
✅ High liquidity, user‑friendly, fiat on‑ramps, customer support.
❌ You don’t control private keys, risk of hacks or freezes, require KYC.
Examples: Uniswap, PancakeSwap, dYdX.
✅ No KYC, you control funds (self‑custody), resistant to censorship.
❌ More complex, lower liquidity for some pairs, you bear full responsibility.
Centralized exchanges typically use an order book – a list of buy and sell orders from users. When you place an order, the exchange matches you with a counterparty. Decentralized exchanges often use automated market makers (AMMs), where you trade against a liquidity pool (smart contracts) instead of another person.
Key takeaway: On a CEX, the exchange holds your funds during trading. On a DEX, you trade directly from your wallet – but you need to understand gas fees and slippage.
