Cryptocurrency Exchanges

What is a cryptocurrency exchange?

A cryptocurrency exchange is a marketplace where you can buy, sell and trade digital assets such as Bitcoin, Ethereum and thousands of altcoins — for other cryptocurrencies or for government-issued (fiat) money like the US dollar. Exchanges match buyers with sellers, hold order books, set the prices you see quoted, and are where the vast majority of crypto trading volume happens.

Centralized (CEX) vs decentralized (DEX) exchanges

A centralized exchange (CEX) — such as Binance, Coinbase or Kraken — is operated by a company that custodies your funds, runs the matching engine and provides a familiar app-like experience. It is the easiest way to start, but you are trusting that operator with your assets and data.

A decentralized exchange (DEX) — such as Uniswap or PancakeSwap — lets you trade directly from your own wallet through smart contracts, with no company holding your coins. You keep custody and privacy, but take on more responsibility: wallet security, network fees and the risk of interacting with a flawed contract. The table above focuses on centralized spot exchanges, where reported volume and Trust Score are most comparable.

How exchanges are ranked here

Exchanges in the table are ordered using CoinGecko's Trust Score and 24-hour trading volume. Trust Score is an independent 0–10 rating that weighs reported versus estimated liquidity, order-book depth, web traffic, API coverage and other signals, to flag venues whose reported volume is credible. We surface this data — we do not assign our own "best exchange" rating or accept payment for placement. A high Trust Score indicates credible liquidity, not a guarantee of safety, regulatory standing or solvency.

How to choose a crypto exchange

• Security & track record: look for a long history without major unresolved hacks, proof-of-reserves, cold-storage practices and two-factor authentication.
• Regulation & region: confirm the exchange legally serves your country and complies with local rules — availability and features vary widely by jurisdiction.
• Fees: compare maker/taker trading fees, spreads, and deposit/withdrawal costs, which add up quickly for active traders.
• Liquidity: deeper markets mean tighter spreads and less slippage for the specific coins you want to trade.
• Supported assets & payments: check the coin is listed and that your preferred funding method (bank transfer, card, stablecoin) is supported.
• Custody: for larger balances, plan to withdraw to a self-custody wallet rather than leaving funds on the exchange.

Spot vs derivatives exchanges

Spot exchanges trade the actual asset for immediate settlement — you own the coin. Derivatives exchanges offer futures, perpetual swaps and options that track an asset's price, often with leverage. Derivatives can amplify both gains and losses and are far riskier; they suit experienced traders, not beginners.

Security & risks to understand

Even top-ranked exchanges carry real risk. Platforms have been hacked, become insolvent, or frozen withdrawals during stress. Regulatory action can restrict access overnight. "Not your keys, not your coins" is the industry's shorthand: assets held on an exchange are ultimately controlled by that exchange. Treat any funds you keep on a trading platform as capital you could lose, and move long-term holdings into self-custody.

How many cryptocurrency exchanges are there?

We currently track 500 exchanges via CoinGecko, of which 500 carry a Trust Score. Across the wider market there are several hundred more small, regional or newly launched venues. The vast majority of real trading volume, however, is concentrated in a few dozen large exchanges — which is why liquidity and Trust Score matter far more than the raw number of platforms.

How crypto exchange fees work

Most exchanges earn money through trading fees, typically split into a maker fee (adding liquidity with a limit order) and a taker fee (removing liquidity with a market order); these usually shrink as your 30-day volume grows. Beyond trading fees, watch three often-overlooked costs: the spread between buy and sell prices, deposit and withdrawal fees (especially on card purchases and fiat withdrawals), and on-chain network fees when moving crypto. For an active trader, the difference between a 0.1% and a 0.5% taker fee compounds quickly — always compare the all-in cost, not just the headline rate.

How to spot a risky or unsafe exchange

Warning signs worth taking seriously include: no clear information about the company, its location or leadership; promises of guaranteed returns or unrealistic bonuses; volume figures that look inflated relative to a low Trust Score; poor or fake reviews; withdrawal complaints; a lack of two-factor authentication or proof-of-reserves; and pressure to deposit quickly. A credible exchange is transparent about who runs it, where it is regulated, how it secures funds, and what happens if something goes wrong. When in doubt, start with a small test withdrawal before committing significant capital.

How crypto exchanges are regulated

Regulation varies enormously by jurisdiction and is still evolving. In the United States, exchanges navigate the SEC, CFTC and state-level money-transmitter licences; the EU is rolling out the unified MiCA framework; the UK requires FCA registration; and hubs like Singapore (MAS), Japan (FSA) and the UAE (VARA) run their own licensing regimes. Some countries restrict specific products (such as leveraged derivatives) or ban crypto trading outright. Because availability and legal protections differ so widely, always confirm an exchange is authorised to serve your country before you sign up.

Spot, margin and derivatives trading

Spot trading is the simplest: you buy or sell the actual asset and own it outright. Margin trading lets you borrow to increase position size, amplifying gains and losses. Derivatives — futures, perpetual swaps and options — are contracts that track an asset's price, usually with leverage. Margin and derivatives can multiply returns but also liquidate a position rapidly in volatile markets; they are tools for experienced traders, not beginners.

Key crypto exchange terms

• Liquidity: how easily an asset can be bought or sold without moving the price. Deep liquidity means tighter spreads and less slippage.
• Order book: the live list of buy and sell orders that determines the market price.
• Maker / taker: whether your order adds liquidity (maker) or removes it (taker) — each carries a different fee.
• Custody: who controls the private keys. On a centralized exchange, the exchange does; in self-custody, you do.
• KYC: "Know Your Customer" identity verification required by most regulated exchanges.
• Proof of reserves: published evidence that an exchange holds enough assets to cover customer balances.
