Over the past few years, the cryptocurrency industry has surged in popularity. While the market offers high-reward opportunities, it also carries significant risks due to its volatility. Prices can fluctuate rapidly, deterring some investors while attracting others seeking lucrative trades.
To trade cryptocurrencies, you’ll need an account on a crypto exchange. These platforms fall into two categories:
- Centralized exchanges (CEX)
- Decentralized exchanges (DEX)
This guide explores centralized exchanges, their functionality, and how they differ from DEXs.
How Does a Centralized Exchange Work?
A centralized crypto exchange (CEX) is an online trading platform managed by a single entity (e.g., a company). Key features include:
- Centralized custody: The platform holds users’ funds and private keys.
- Order matching: Uses an order book to pair buy/sell requests.
- Identity verification (KYC): Mandatory for compliance with regulators.
- Security measures: Funds are stored in cold storage (offline) with minimal assets in hot wallets for liquidity.
