Hot vs cold wallet: where should your crypto live?

A crypto wallet doesn't hold coins. It holds the keys that prove the coins are yours. A hot wallet keeps those keys on a device that's online. A cold wallet keeps them offline. That one difference decides most of your risk.

The short answer

A hot wallet is connected to the internet. It's an app on your phone, a browser extension, or a desktop program. It's quick to use and handy for trading.

A cold wallet keeps your keys offline. Usually it's a small hardware device that only signs transactions when you plug it in and press a button.

Hot is convenient. Cold is harder to steal from. Many people use both: a little in hot, the rest in cold.

Side by side

First: what a wallet really is

Your coins live on the blockchain. The wallet holds your private key, the secret that lets you move them.

When you set up a wallet, it shows you a recovery phrase (also called a seed phrase), usually 12 or 24 words. Those words can rebuild your wallet on any device.

Here's the thing. Whoever has those words has your coins. That's true for hot and cold wallets alike.

Hot wallets, in plain words

The good parts:

• Fast. Send, receive or swap in seconds.
• Free. Most wallet apps cost nothing.
• Works with apps. You need one to use a decentralized exchange. See centralized vs decentralized exchange.

The limits:

• Online means reachable. Malware, fake apps and phishing sites target hot wallets.
• One bad click. Signing a harmful transaction can empty the wallet.
• Phone risk. A lost or hacked phone can expose the wallet if it isn't locked well.

Cold wallets, in plain words

The good parts:

• Keys never touch the internet. Even if your computer has malware, the device must approve each send.
• You see and confirm on the device. The address shows on its own screen.

The limits:

• Costs money. Hardware wallets are paid devices.
• Slower. More steps for each transaction.
• You are the backup. Lose the device and the phrase, and nobody can help.
• Fake devices exist. A tampered device can come with a phrase already set.

Safety checks before every send

1. Check the address on the device screen, not just on your computer.
2. Compare the first and last several characters. Some scams plant look-alike addresses in your history.
3. Send a small test amount first for a new address.
4. Check the network. Sending a coin on the wrong network can lose it.
5. Don't rush. Scams almost always come with pressure to act fast.

Setting up a cold wallet safely

• Buy directly from the maker, not from a second-hand seller.
• Set it up yourself. If a phrase comes already printed in the box, don't use it.
• Write the phrase down once, by hand, and check it.
• Test recovery with a small amount before moving more.

Which fits you?

1. Just starting, with a small amount? A well-known hot wallet, or a regulated exchange, while you learn. Keep it small.
2. Holding an amount that would hurt to lose? Many people move it to a cold wallet.
3. Trading often? Keep only your trading amount hot. The rest cold.

Leaving coins on an exchange is a third choice: the exchange holds the keys. It's simple, but you depend on the company. See the FTX collapse.

And whatever wallet you use, crypto prices can swing hard, 24/7. Only risk what you can afford to lose.

Common mistakes

• Saving the recovery phrase as a photo or in a cloud note.
• Downloading a wallet from an ad. Search results and ads can point to fake apps. Use the official site.
• "Support" in your messages. Real support never DMs you first and never asks for your phrase.
• Skipping the test send. A few cents of fee can save a costly mistake.
• Telling people how much you hold. It makes you a target.
