Cryptocurrency trading has expanded significantly despite ongoing regulatory pressure, market volatility, and the high-profile failures of several major platforms in 2022. For anyone new to crypto, understanding how exchanges work — and how different types of exchanges differ in their trade-offs — is an essential first step. This is Part 1 of a two-part guide. It covers what exchanges are and the main types available. Part 2 covers the seven factors to evaluate when choosing a specific platform.
What Is a Crypto Exchange?
A cryptocurrency exchange is a platform where you can buy, sell, or trade digital assets. For most people, acquiring crypto through an exchange is more practical than mining it. Exchanges are accessible through web browsers or mobile apps, and they vary significantly in their features, fee structures, regulatory status, and the coins they support.
Beyond basic trading, many exchanges offer additional services: margin accounts and futures trading for experienced investors, staking, lending, custodial wallet services, and NFT marketplaces. Not every coin is available on every exchange — if you want to acquire Monero specifically, you need to verify that your chosen platform lists XMR and supports on-chain withdrawal before signing up.
Centralized Exchanges (CEX)
A centralized exchange is run by a company that acts as an intermediary between buyers and sellers. CEXs operate as regulated businesses required to comply with local laws — including Know Your Customer (KYC) identity verification and Anti-Money Laundering (AML) reporting requirements. Examples include Binance, Kraken, Gemini, and Bitfinex.
The strengths of CEXs include speed (centralized servers execute trade orders quickly), fiat on-ramps (bank accounts, credit cards, and payment apps are accepted), high liquidity (large user bases create deep markets with tight spreads), and user-friendly interfaces with customer support.
The weaknesses are significant for privacy-conscious users. KYC requirements link your real identity to your exchange account and every purchase made through it. CEXs are custodial: when you hold crypto on an exchange, you hold a claim against the exchange, not the underlying coins. The FTX collapse in 2022 — which resulted in billions of dollars of user funds becoming inaccessible — illustrated how serious this distinction is in practice. CEXs are also subject to regulatory sanctions, and several have delisted privacy coins including Monero due to compliance challenges.
Decentralized Exchanges (DEX)
A decentralized exchange operates through smart contracts on a blockchain without a central company controlling funds or governance. Users connect their own wallets and trade directly with other users, retaining full asset custody throughout. DEXs do not require KYC. Examples include Uniswap, SushiSwap, and PancakeSwap for Ethereum-based assets, and Haveno DEX for Monero.
DEX strengths for privacy-focused users: no KYC, non-custodial (you control your keys at all times), censorship-resistant (regulators cannot easily block individual transactions), lower or no intermediary fees, and access to a broader range of coins including those that regulated CEXs decline to list.
DEX weaknesses: lower liquidity than major CEXs, no fiat on-ramp (you can only trade crypto for crypto), more complex interfaces, limited advanced trading features such as margin and futures, and no customer support — issues must be resolved by users themselves.
A Note on Monero and Exchanges
Monero presents a specific exchange consideration: because XMR's mandatory privacy features make compliance with travel rule reporting requirements difficult, several CEXs have delisted it. This has shifted XMR acquisition toward decentralized options — notably Haveno DEX (built specifically for Monero P2P trading), Bitcoin-to-Monero atomic swaps via the COMIT tool, and remaining CEXs that still list XMR in supported jurisdictions.
Regardless of how you acquire XMR, withdrawing to a non-custodial wallet is the appropriate next step. XMRWallet is free, open-source, and requires no registration — create it before you begin trading so you have a withdrawal address ready.
Part 2 of this guide covers the seven factors to evaluate when choosing between specific exchange platforms: jurisdiction, reputation, security, liquidity, coin availability, fees, and user interface. Read Part 2 here.
Frequently Asked Questions
Is it safe to keep crypto on an exchange long-term?
For anything beyond actively traded amounts, no. Exchange custody means you hold a claim against the exchange rather than owning the underlying coins. Platform failures (FTX, Celsius, Voyager in 2022; earlier examples going back to Mt. Gox in 2014) have resulted in users permanently losing access to funds held on exchanges. Withdraw to a non-custodial wallet for any assets you plan to hold rather than trade in the near term.
