Plain-English guides to picking an exchange, making your first purchase and keeping your coins safe.
The process is almost the same on every exchange. Read it once and you will know what to expect.
See it in practice: how to buy cryptoPick a platform that is registered where you live (check the register first) and accepts your payment method. Compare the total cost before you sign up.
Most exchanges ask for photo ID, and sometimes proof of address, before you can buy. This check is called KYC.
Deposit with a bank transfer, card or another supported method. Cards are usually faster, but they often cost more.
Choose a coin and enter an amount in your own currency. You can buy a small fraction, so there is no need to buy a whole Bitcoin.
Keep small amounts on the exchange or move them to a wallet you control. Write your recovery phrase (also called a seed phrase) down and keep it offline.

Exchanges, broker apps and decentralized exchanges all sell crypto. They differ in who holds your coins and what they check.
A company matches buyers and sellers and holds your funds while they are on the platform.
You buy crypto inside a finance or payment app, usually at a price that includes a wider spread.
Smart contracts swap tokens straight from your own wallet, with no company holding your funds.

For most beginners, a centralized exchange or a regulated broker app is the simplest route: create an account, verify your identity, add money and choose a coin.
Very little. Most exchanges let you buy a fraction of a coin, and many have low minimum purchases. Only invest money you can afford to lose, because crypto prices can swing sharply.
Exchanges can be hacked or go out of business, and you rely on them to return your coins. Many people keep only what they actively trade on an exchange and move the rest to a wallet where they control the private keys.
On most centralized exchanges, yes. Know Your Customer (KYC) checks are required by anti-money-laundering rules in many countries. Decentralized exchanges usually do not ask for ID, but you need a wallet and some crypto to use them.
Expect a mix of trading fees, the spread (the gap between the buy and sell price), deposit or card fees, and withdrawal fees. Compare the total cost of a purchase, not only the headline trading fee.
In many countries, yes. Selling, swapping or spending crypto can count as a taxable event. The rules differ from country to country, so check with your local tax authority or a tax professional.
