Crypto Exchange

A platform that allows users to buy, sell, and trade cryptocurrencies for other digital assets or fiat currencies like USD or EUR.

A cryptocurrency exchange is an online marketplace where traders can convert cryptocurrencies into other assets. There are two main types: **centralized exchanges (CEX)** like Coinbase and Binance, which act as intermediaries and hold your funds, and **decentralized exchanges (DEX)** like Uniswap, which allow peer-to-peer trading without intermediaries.

How Crypto Exchanges Work

Centralized exchanges operate similarly to stock exchanges. They maintain order books matching buyers and sellers, provide custody of funds, and typically require identity verification (KYC). DEXs use smart contracts on blockchain networks to facilitate trades directly between users' wallets.

Key Features to Look For

  • **Fees**: Trading fees typically range from 0.1% to 1.5% per trade
  • **Supported coins**: Major exchanges list 200-500+ cryptocurrencies

FAQ

Is a crypto exchange safe?

Reputable exchanges employ bank-level security including cold storage, 2FA, and insurance funds. However, you should never store large amounts on an exchange long-term — use a hardware wallet for holdings you don't actively trade.

What fees do crypto exchanges charge?

Most exchanges charge 0.1% to 1.5% per trade, with maker fees (limit orders) typically lower than taker fees (market orders). Some also charge withdrawal fees and deposit fees for certain payment methods.
