Core principles

Ten rules that hold up everything else

If you remember nothing else from this guide, remember these. Each links to the page that goes deeper.

  1. 01

    Not your keys, not your coins

    Bitcoin on an exchange is an IOU. It’s only truly yours when you hold the keys.

  2. 02

    The seed phrase is the wallet

    The device is replaceable — lose or break it and you restore from your words. The words are the money.

  3. 03

    The simplest setup that covers you wins

    Not the most impressive, not the one a vendor sells. The simplest one that defends against the risks you can name.

  4. 04

    More complexity isn’t more security

    Complexity is the single biggest cause of lost Bitcoin. Climb the ladder only for a real reason.

  5. 05

    A backup you haven’t tested is a hope

    Wipe and restore with a tiny amount before you trust it with savings. Prove it, don’t assume it.

  6. 06

    Never let your seed touch anything digital

    No photo, no cloud, no typing it into a phone or computer — not even for a minute.

  7. 07

    Verify the address on the device’s own screen

    Your computer can be fooled by malware. The hardware wallet shows the truth. Check it every time.

  8. 08

    Don’t talk about your Bitcoin

    The best physical protection is not being known as a holder. Share the idea, not your holdings.

  9. 09

    Plan for the day you’re gone

    Most lost Bitcoin isn’t stolen — it’s left behind with no instructions. Leave a plan your family can follow.

  10. 10

    Verify, don’t trust

    When you’re ready, run your own node so you check Bitcoin’s rules yourself instead of trusting someone’s server.

And the one that contains them all

Verify. Don’t trust. Everything here is one expression of that idea — check your backup, check the address, check the rules, and don’t take anyone’s word for what’s yours.
