Buying crypto on a TV, computer or smartphone
What works on each device, and what to watch out for.
The steps for buying cryptocurrency are the same whatever device you use: create an account with an exchange, verify your identity, add money, then place an order. What differs is how convenient and how secure each device is. Our beginner's guide covers the steps in detail.
On a computer
A laptop or desktop is the most flexible way to buy. You use the exchange's website in a browser, and the larger screen makes it easier to compare prices, read the fees, and check every detail before you confirm an order.
- Good for: setting up and verifying an account, bigger purchases, and reading the small print.
- Stay safe: type the exchange's address yourself or use a bookmark rather than clicking links in emails or adverts, keep your system and browser updated, and use security software. Be careful about browser extensions you don't need.
On a smartphone
Most exchanges have an app, and many people find it the easiest way to buy. Identity checks are often quicker, because you can photograph your ID and take a selfie with the same device, and you can log in with your fingerprint or face.
- Good for: everyday purchases, price alerts and checking the market on the go. See how to follow prices on your phone.
- Stay safe: download apps only from the official App Store or Google Play, after checking the developer's name, since fake apps exist. Use a passcode or biometrics, keep the phone's software updated, and turn on two-factor authentication. If you lose your phone, be ready to lock your account quickly.
On a TV
Here we need to be honest: buying crypto on a television is generally not a practical or recommended option. As far as we know, major exchanges don't offer buying through dedicated apps on smart TVs. Some smart TVs have a web browser, so you could technically open an exchange's website on one, but it is a poor idea:
- Typing passwords with a remote control is slow, and onlookers or other people in the household can see your screen.
- TVs often get fewer security updates than phones and computers, and may not support the security features exchanges expect.
- Logging in and passing identity checks is awkward without a keyboard and camera.
What a TV is good for is watching. You can open this site's rates page in a TV browser, or cast or mirror your phone or computer screen to the TV, to view prices and charts on a big screen. Do the actual buying on your phone or computer. If a particular TV app or service claims to let you buy crypto, check the company carefully, as scams often use unfamiliar platforms.
Which device should you use?
- First-time set-up: a computer, for the larger screen and careful reading.
- Day-to-day buying and alerts: your smartphone.
- Watching the market: a TV, by casting from another device.
Whichever you choose, only invest money you can afford to lose, since crypto prices can fall sharply. Not sure which coin to look at? Read about Bitcoin, Ethereum, Dogecoin or EOS. If you plan to hold coins for a long time, read our guide to wallets.
