When you start a exchange comparison, the practice of measuring crypto platforms on fees, security, features and liquidity. Also known as platform evaluation, it gives traders a clear view of which service fits their style. A solid crypto exchange, a centralized service that lets you buy, sell, and trade digital assets usually offers deep order books and fiat on‑ramps, while a decentralized exchange, a peer‑to‑peer protocol that runs on‑chain without a custodian gives you control over private keys. Exchange comparison also means looking at trading fees, the cost taken from each trade, often expressed as a percentage of volume and how those fees change with volume tiers. Lastly, you must weigh exchange security, measures like insurance, audit history and two‑factor protection that guard your funds to avoid costly hacks. Together these pieces form the core of an exchange comparison and help you avoid common pitfalls.
