What Is a Crypto Exchange?

A crypto exchange is a platform where users can exchange money (fiat or crypto) for digital assets. Exchanges provide price discovery, liquidity, wallets for deposits/withdrawals, and interfaces for placing orders. Some are centralized (operate like regulated marketplaces), while others are decentralized (smart-contract based).

Before trading, review basic risk controls in Crypto Trading for Beginners.

Types of Crypto Exchanges

1) Centralized Exchanges (CEX)

Operated by companies that custody assets and run matching engines. Pros: high liquidity, fiat on‑ramps, customer support, mobile apps. Cons: custodial risk, KYC requirements, regional restrictions.

2) Decentralized Exchanges (DEX)

On‑chain protocols (e.g., AMMs) where users swap assets via smart contracts and self‑custody wallets. Pros: no centralized custodian, permissionless access. Cons: slippage on thin pools, on‑chain fees, smart‑contract risk.

3) Peer‑to‑Peer (P2P) Marketplaces

Users trade directly with each other using escrow services. Pros: flexible payment methods, useful in underbanked regions. Cons: settlement risk if counterparty disputes, need strong escrow rules.

4) Hybrid/Broker Models

Combine CEX convenience with non‑custodial options, or aggregate DEX liquidity behind a centralized UI. Pros: better UX; Cons: mixed trust model.

How Exchanges Work (Order Books, AMMs, Custody)

Order Books & Matching Engines

CEXs maintain order books with bids/asks. A matching engine pairs buy and sell orders by price/time to execute trades. Depth and spread determine execution quality.

AMMs (Automated Market Makers)

DEXs use liquidity pools and algorithms (x*y=k and variants) to quote prices. Swaps occur against the pool; liquidity providers earn fees but face impermanent loss when prices move.

Custody vs Self‑Custody

On CEXs, assets are typically held in pooled wallets (with cold‑storage reserves). On DEXs, you keep funds in your own wallet and sign transactions. Choose based on your need for convenience vs sovereignty.

Exchange Fees Explained

  • Maker/Taker: Makers add liquidity; takers remove it. Fees usually depend on monthly volume or VIP tiers.
  • Deposit/Withdrawal: Network fees for blockchain transactions; some fiat methods carry bank/processor costs.
  • Funding (Perpetuals): Periodic payments between longs/shorts to balance prices with spot.
  • Hidden Costs: Slippage on thin books/pools, spreads, conversion and off‑chain transfer fees.
  • Discounts: Holding or spending platform tokens (e.g., BNB, OKB) can reduce trading fees.

Security & Regulation

  • Account Security: Enable 2FA (authenticator app), withdrawal whitelists, and anti‑phishing codes.
  • Custody Practices: Cold‑storage reserves, segregated accounts, proof‑of‑reserves attestations.
  • Compliance: KYC/AML requirements vary by region; check restricted countries and licensing.
  • Smart‑Contract Safety (DEX): Audit reports, bug bounties, timelocks, multisig controls.
  • Personal Hygiene: Use strong passwords, secure devices, beware of fake apps/links.

Where to Trade (Recommended Platforms)

FAQs

Is a CEX or DEX better for beginners?

CEXs are usually easier (fiat on‑ramps, support, mobile apps). DEXs offer self‑custody and permissionless access but require more responsibility.

Do I always need KYC?

CEXs generally require KYC depending on region and features. Most DEXs don’t require KYC, but you must manage your own wallet security.

Is it safe to keep coins on an exchange?

Exchanges can be convenient, but long‑term holders often prefer self‑custody. If you keep funds on a CEX, use all security features and monitor announcements.

What fees should I watch?

Maker/taker trading fees, deposit/withdrawal costs, funding (for perps), and slippage on thin markets. Check official fee pages regularly.
