A crypto wallet doesn’t actually “hold” your coins the way a real wallet holds cash. Instead, it stores the keys that prove the coins on the blockchain belong to you.
Public key vs private key
Think of your public key (or address) like an email address — you can share it so people can send you crypto. Your private key is like your password: anyone who has it can move your funds. Never share it with anyone.
Your seed phrase is everything
When you set up a wallet, you get a seed phrase — usually 12 or 24 words. This phrase can restore your entire wallet, so:
- Write it down on paper and store it somewhere safe and offline.
- Never take a screenshot or store it in your email or notes app.
- No legitimate service will ever ask you for it.
Hot wallets vs cold wallets
Hot wallets are connected to the internet — phone apps and browser extensions. They’re convenient for everyday use, but being online makes them more exposed.
Cold wallets are kept offline, usually on a dedicated hardware device. They’re much harder to hack and are best for storing larger amounts you don’t need to touch often.
A simple rule of thumb
Keep small, spendable amounts in a hot wallet for convenience, and store the rest in cold storage. Whatever you choose, your seed phrase is the master key — protect it above all else.
