How do crypto exchanges work and which are most reliable?

Crypto exchanges are platforms where users buy, sell, and trade cryptocurrencies. They work like traditional stock exchanges: you create an account, deposit money (fiat or crypto), and place orders to trade. Most exchanges use an order book system matching buyers and sellers. Reliable exchanges typically have strong security, regulatory compliance, high trading volume, and transparent fee structures. Major established platforms include Coinbase, Kraken, and Binance, which serve millions of users globally. When choosing an exchange, consider factors like security certifications, insurance coverage, geographic restrictions, supported coins, and fee schedules. Always use two-factor authentication and consider storing large amounts in separate wallets for additional safety.
