Welcome to Lesson Two.
In the last lesson, you learned what crypto really is. Now it’s time to learn how to protect it.
Your coins live on the blockchain, but you still need a way to access them — and that’s what a wallet does.
A crypto wallet isn’t like the one in your pocket.
You don’t actually store coins inside it — your coins always stay on the blockchain.
Think of your wallet as a keyring. Each key gives you access to your crypto. If you have the keys, you’re in control. Lose the keys, and it’s gone for good.
There are two main types of wallets: hot and cold.
A hot wallet is connected to the internet. It’s fast and convenient — perfect for trading or moving funds quickly — but also more exposed to hackers.
It’s like keeping cash in your front pocket: easy to grab, easy to use, but not where you’d store large amounts long-term.
A cold wallet stays completely offline, usually as a small hardware device.
It’s like keeping your money in a home safe — less convenient, but far more secure.
