If you've read my previous guide on Bitcoin Wallets for Beginners, you already understand crypto wallets—how to set one up and how to send/receive Bitcoin.
But what if you don’t own any Bitcoin yet?
How do you buy Bitcoin?
To purchase Bitcoin, you’ll need to open an account on a cryptocurrency exchange.
A cryptocurrency exchange is a marketplace where buyers and sellers trade digital currencies. These platforms provide a trading interface, typically as a website or mobile app, where you can buy, sell, or exchange cryptocurrencies.
Cryptocurrency exchanges are also called Crypto Trading Platforms (CTP).
Before exchanges existed, acquiring Bitcoin (and other cryptocurrencies) required mining, negotiating peer-to-peer deals on forums, or even in-person cash transactions.
Today, most beginners enter the crypto space through exchanges. These platforms make it fast and easy to buy Bitcoin with just a few clicks.
There are many types of exchanges—some cater to beginners, while others serve advanced traders.
Different exchanges support different cryptocurrencies, so you may need multiple platforms depending on your trading goals.
This guide explains how cryptocurrency exchanges work and helps you choose the right one.
What is a Cryptocurrency Exchange?
A cryptocurrency exchange is a digital platform where users trade one cryptocurrency for another.
More specifically, it’s an online marketplace for buying, selling, and exchanging cryptocurrencies.
These platforms are called “exchanges” because they match buyers and sellers without taking ownership of assets. They earn revenue by charging fees per transaction.
Depending on the exchange, you can:
- Buy cryptocurrencies using fiat money (e.g., USD).
- Swap one cryptocurrency for another (e.g., BTC to LTC).
- Sell crypto and withdraw funds.
Types of Cryptocurrency Exchanges
Broadly, “exchange” describes any platform enabling currency conversion.
However, in crypto, there are two main types:
- Centralized Exchanges (CEX)
- Decentralized Exchanges (DEX)
Which is better for beginners? Let’s compare them.
Centralized Exchanges (CEX)
Centralized cryptocurrency exchanges (CEX) operate like traditional trading platforms. Users create accounts to trade, send/receive, and store assets like Bitcoin (BTC).
CEXs are businesses that custody user funds and comply with financial regulations. They enable bank transfers for deposits/withdrawals and offer customer support.
Decentralized Exchanges (DEX)
Decentralized exchanges (DEX) let traders swap cryptocurrencies peer-to-peer without intermediaries.
DEXs are software protocols running on blockchain networks. Users connect self-custody wallets to trade directly. Prices are set by automated algorithms (smart contracts).
Unlike CEXs, DEXs:
- Are non-custodial (users control assets).
- Operate without central authority.
- Settle trades on-chain.
However, they require technical knowledge and lack customer support.
CEX vs. DEX: Which Should You Choose?
Both charge fees, but CEXs are more beginner-friendly:
- Fiat on/off-ramps.
- Regulatory compliance.
- Customer service.

DEXs suit advanced users familiar with DeFi. They involve higher risks, like smart contract vulnerabilities.
For beginners, start with a CEX.
FAQ
1. What is the safest cryptocurrency exchange?
Reputable CEXs like Coinbase and Binance prioritize security (e.g., cold storage, 2FA). Always enable security features.
2. Can I withdraw crypto from an exchange to my wallet?
Yes! Withdraw to a private wallet for full control. Avoid long-term exchange storage.
3. Are decentralized exchanges illegal?
No, but regulations vary. Research local laws before using DEXs.
4. Which exchange has the lowest fees?
Compare fee structures. Some CEXs offer discounts for native tokens (e.g., BNB on Binance).
