A wallet is software that holds your keys. Setting one up takes ten minutes, but the backup step deserves care.
1. Pick a wallet
For a first wallet, a reputable self-custody app on your phone is fine for small amounts. Download it only from the official app store or the maker's site, and check the developer name, because fake wallet apps exist.
2. Create a new wallet
The app generates a seed phrase of 12 or 24 words (BIP39). These words are your bitcoin: anyone with them can take the coins, and if you lose them and your phone, nobody can help you.
3. Back up on paper
- Write the words in order, by hand.
- No screenshots, no cloud notes, no email.
- Store the paper somewhere safe from fire, water and curious eyes.
Many wallets let you add an optional passphrase. It adds protection, but if you forget it, the coins are gone.
4. Test the backup
Send a small amount in. Then test recovery: many wallets have a "verify backup" step, or you can restore the words in a second wallet and check that the same addresses appear.
5. Receive
Tap "Receive" to get a bitcoin address, usually starting with bc1. You can share it as text or as a QR code.
Growing up
As your savings grow, move to a hardware wallet. Your seed phrase standard stays the same, so learning it now pays off later.
Takeaway
The app is replaceable; the seed phrase is not. Protect the words and test that they work.
