How Do Crypto Exchanges Work?
Centralized exchanges operate similarly to stock brokerages. You create an account, verify your identity (KYC), deposit funds via bank transfer or card, and place orders to buy or sell crypto. The exchange matches your order with a counterparty, executes the trade, and holds your assets in a custodial wallet. Decentralized exchanges work differently — they use liquidity pools and automated market makers instead of order books, and you trade directly from your own wallet.
What Should You Look for in a Crypto Exchange?
Key factors include security track record (has the exchange been hacked?), regulatory compliance and licensing, fee structure (trading fees, withdrawal fees, spread), available cryptocurrencies, liquidity depth, user interface quality, and customer support responsiveness. Also consider whether the exchange offers features you need: staking, lending, advanced order types, or tax reporting tools. US-based, regulated exchanges generally offer stronger consumer protections.
Should You Keep Crypto on an Exchange?
The industry mantra "not your keys, not your coins" reflects the risk of leaving assets on exchanges. Exchange hacks and collapses (Mt. Gox, FTX) have cost users billions. For small trading amounts, exchange custody is convenient. For significant holdings, transfer to a personal cryptocurrency wallet — ideally cold storage — where you control the private keys and are not dependent on any company's solvency.

What fees do crypto exchanges charge?
Most exchanges charge trading fees of 0.1%-1.5% per transaction, with maker-taker models offering lower fees to liquidity providers. Additional fees may apply for deposits (especially credit card purchases), withdrawals, and currency conversions. Fee structures vary significantly between platforms.
