What Is a Crypto Exchange?
A cryptocurrency exchange is a digital marketplace where users can buy, sell, and trade cryptocurrencies like Bitcoin, Ethereum, and altcoins. These platforms act as intermediaries, facilitating transactions between buyers and sellers while supporting fiat-to-crypto conversions (e.g., USD to BTC). Unlike traditional stock exchanges, crypto exchanges cater specifically to digital assets, offering tools tailored for volatility and 24/7 trading.
Key Features:
- Order matching: Connects buyers/sellers via an order book.
- Liquidity pools: Ensure smooth transactions.
- Security protocols: Include cold storage and encryption.
How Crypto Exchanges Work
Exchanges operate using an order book system:
- Buy/Sell Orders: Traders place limit or market orders.
- Matching Engine: Pairs compatible orders automatically.
- Settlement: Cryptocurrencies or fiat are transferred upon trade execution.
Centralized (CEX) vs. Decentralized (DEX):
| Type | Pros | Cons |
|---------------|-------------------------------|-------------------------------|
| CEX | User-friendly, high liquidity | Custodial risk |
| DEX | Non-custodial, private | Lower liquidity, complex UI |
Types of Crypto Exchanges
Centralized Exchanges (CEX):
- Managed by a company (e.g., Binance, Coinbase).
- Offer margin trading, staking, and customer support.
Decentralized Exchanges (DEX):
- Peer-to-peer via smart contracts (e.g., Uniswap).
- Prioritize security and anonymity.
