A cryptocurrency exchange is an online platform where users buy, sell, and trade digital assets like Bitcoin and Ethereum. These exchanges serve as the backbone of the crypto ecosystem by ensuring market liquidity, providing real-time trading tools, and bridging the gap between fiat currencies and cryptocurrencies.
Key Takeaways
- Cryptocurrency exchanges facilitate secure trading of digital assets, offering features like staking, fiat integration, and advanced order types.
- There are three primary exchange types: Centralized (CEX), Decentralized (DEX), and Hybrid—each with distinct advantages in security, liquidity, and user control.
- Critical factors when choosing an exchange include liquidity, fees, security protocols, regulatory compliance, and customer support.
How Does a Cryptocurrency Exchange Work?
Exchanges match buyers and sellers via an order book listing active bids/asks. Users can execute:
- Market orders: Immediate trades at current prices.
- Limit orders: Trades triggered only at specified price levels.
Funds are typically stored in cold wallets (offline) to minimize hacking risks. To start trading, users must:
- Register and complete KYC verification.
- Deposit fiat or crypto.
- Place orders, which the exchange matches for settlement.
