What Does a Crypto Exchange Do?
A crypto exchange is a digital platform where users can buy, sell, and trade cryptocurrencies like Bitcoin (BTC), Ethereum (ETH), and hundreds of altcoins.
Just like a traditional stock exchange facilitates the buying and selling of company shares, a crypto exchange:
- Matches buyers and sellers using a trading engine
- Lists real-time prices and charts for every asset pair
- Manages custodial or non-custodial wallets, depending on the platform type
- Enables fiat onramps and offramps (e.g., USD → BTC or BTC → EUR)
- Provides trading infrastructure for spot, margin, and sometimes derivatives markets
- Maintains order books and ensures liquidity for listed assets
- Implements KYC/AML verification to meet legal standards (on CEXs)
Some exchanges also support staking rewards, DeFi integration, and on-chain analytics tools to help users make informed decisions. These features often help traders better time their entries, identify trends, and diversify their crypto strategies.

How Crypto Exchanges Generate Liquidity
Crypto exchanges use order books to match buy and sell offers in real-time. Liquidity refers to how easily assets can be bought or sold without causing large price movements.
Many centralized exchanges (CEXs) partner with market makers—entities that continuously provide buy and sell orders—to ensure trades are always available.
Other key components that influence liquidity and execution speed include:
- Matching engines: Software that processes thousands of trades per second
- Liquidity pools: Especially on DEXs or hybrid platform
- Slippage control: Tools to manage price impact during order execution
Centralized vs. Decentralized Exchanges (CEX vs. DEX)
There are two major types of crypto exchanges: centralized (CEX) and decentralized (DEX). Some newer platforms also fall into a hybrid category, combining centralized onboarding with decentralized custody or trading (e.g., dYdX).

In short:
- CEXs like XBO are ideal for users who value ease, speed, and access to fiat deposits/withdrawals.
- DEXs are better suited for privacy-focused or DeFi-native users.
How Crypto Exchanges Work (Step-by-Step)
Let’s walk through a typical user journey using an example:
Example: Alice is new to crypto. She signs up for XBO, completes verification, deposits $500 via bank transfer, and places an order to buy $250 worth of Ethereum. Within seconds, her order executes, and she sees ETH in her portfolio. A week later, she withdraws it to her hardware wallet.
Most CEXs, including XBO, follow this basic process:
- Sign Up & Verify: Create an account and complete KYC (Know Your Customer) verification
- Deposit Funds: Transfer fiat (e.g., USD) or crypto to your exchange wallet.
- Place an Order: Choose a market or limit order to buy/sell your desired crypto.
- Trade Execution: The platform matches your order in real-time using an order book.
- Withdraw: Move your funds to your personal wallet or bank account.
Order Types Explained
- Market Order: Buys or sells immediately at the current best available price
- Limit Order: Sets a specific price—you only trade if the market hits it
- Stop Order: Triggers a buy or sell when a certain price is reached (often used for risk management)
