Day 5 of my crypto learning series
When people decide to buy their first crypto, the first question is usually “where do I buy it?” For most beginners, the answer is a crypto exchange. But I realized something while learning: choosing the exchange is just as important as choosing what to buy. Here is what I learned, in simple words.
What is a crypto exchange?
A crypto exchange is a platform where you can buy, sell, and trade cryptocurrencies like Bitcoin ($BTC) and Ethereum ($ETH). It sits in the middle between buyers and sellers, a bit like a marketplace. You create an account, add money, and place an order.
Remember Day 3? This is where it matters
On Day 3, I learned the difference between custodial and non-custodial wallets. Most exchange accounts are custodial. That means the company holds the keys to your crypto, not you. This is convenient. You can log in with a password, and the company can help if you get locked out. But it also means you are trusting that company to protect your money. That is why choosing carefully matters.
6 things to check before you trust an exchange
1. Security. Look for two-factor authentication (2FA). This means that to log in you need your password plus a code from your phone. A password alone is easier to steal. Good exchanges also keep most customer funds in “cold storage,” which means offline, away from hackers.
2. Proof of reserves. This is a report showing that the exchange really holds the assets it says it holds for its users. It is not a guarantee of safety, but it is a good sign of transparency. An exchange that hides everything is a worse sign.
3. Rules and licensing. Check whether the exchange follows the laws of the country where you live. Rules differ a lot from country to country, so look up your own. Many exchanges ask for ID verification (KYC). That can feel annoying, but it is normal.
4. Fees. Most beginners only look at trading fees. But there can also be deposit fees and withdrawal fees. Some exchanges advertise low trading fees but charge more elsewhere. Read the whole fee page before you start.
5. Withdrawals. Can you move your crypto to your own wallet whenever you want? Before putting in a large amount, test with a very small one. If withdrawing is slow or confusing, think twice.
6. Support and history. Can you reach a real person if something goes wrong? How did the company handle problems in the past? A clear history is better than big promises.
Mistakes beginners can avoid
Choosing the biggest name only. Popular does not automatically mean safest. Check the six points above anyway.Skipping 2FA. It takes two minutes to turn on and adds a strong layer of protection. Use an authenticator app if you can.Clicking links in messages. Fake websites can look exactly like real ones. Type the official address yourself or use the official app.Sharing sensitive information. A real exchange will never ask for your password, your 2FA code, or your seed phrase. If someone does, it is a scam. (We covered this on Day 4.)Leaving everything on the exchange without thinking. For small amounts you are learning with, it may be fine. But understand the trade-off: if you don’t hold the keys, you rely on the company.
A simple starting routine
Pick an exchange using the six checks.Turn on 2FA before you add any money.Start with a small test amount.Practice a test withdrawal to your own wallet.Keep learning before you put in more.
Final thoughts
An exchange is a tool, not a guarantee. It can make buying crypto easier, but the safest approach is to check, start small, and stay careful. I am not recommending any specific exchange in this series. Please do your own research and check the rules in your country.
This is learning, not financial advice. Crypto prices can swing a lot, and you can lose money.
Question for you: Day 6 is about price and market cap. Have you ever thought a coin was “cheap” just because its price was low? Tell me below 👇
