What Is a Crypto Exchange?

A crypto exchange is a platform where you can buy, sell, and trade cryptocurrencies. For most people, it's the first step into crypto, and choosing the right one, and using it carefully, matters more than many beginners realize.

What an Exchange Does

Exchanges connect buyers and sellers, convert traditional money into crypto and back, and let users trade one cryptocurrency for another. Many also offer extra services like staking, savings products, or derivatives trading.

Centralized Exchanges

A centralized exchange (CEX) is run by a company. You create an account, usually verify your identity, deposit funds, and trade through the exchange's platform. The exchange holds your crypto while it's on the platform, which is convenient but means trusting the company.

Decentralized Exchanges

A decentralized exchange (DEX) runs on smart contracts. You trade directly from your own wallet, usually against liquidity pools, without an account. Each type has its own trade-offs in control, convenience, and risk.

What to Look For in a Centralized Exchange

Whether it's authorized to operate in your country, its track record with security incidents, whether it publishes proof of reserves, its fees, and how reliably it processes withdrawals.

Fake Exchanges Are Common

Many scams use convincing fake exchange websites that show fabricated profits and block withdrawals, often with demands for a "tax" or "fee" to release funds. A professional-looking site proves nothing. Fake exchanges are especially common in romance scams and "investment mentor" schemes.

Using an Exchange Safely

Access it through a saved bookmark or official app, enable two-factor authentication, use a unique password, never share login details or codes, and be wary of anyone contacting you as "support."

Don't Treat an Exchange as a Vault

Exchanges can be hacked, freeze withdrawals, or fail. Many experienced users keep only what they're actively trading on an exchange and move the rest to a wallet they control.

Check an unfamiliar exchange's domain and legitimacy before depositing. The right exchange is a useful tool; the wrong one is a trap.
