Writing down your seed phrase

I want you to fully focus for the next few minutes. Put your phone on silent. Don't multitask. This is the lesson where 90% of people who lose Bitcoin lose it. We're going to do it right.

Open your wallet. If you closed it after lesson four, create a fresh wallet now and come back when you see the screen with the twelve or twenty-four words on it.

Got it? Good.

Here's the rule: your seed phrase must live on paper. Not in your phone. Not on your computer. Not in a screenshot. Not in your email. Not in your password manager. Not photographed. Not in the cloud. Paper.

Why paper? Because every other option can be stolen by someone who's never been in your house. Your phone gets hacked, your photos sync to the cloud, your password manager has a breach. Paper doesn't have any of those failure modes. Paper requires someone to physically come to your house and find it.

So — get a piece of paper, and a pen. Not a pencil; pencil fades. A normal ball-point pen is perfect.

Now, looking at the wallet screen, write the words down. In order. With the numbers next to them. So your paper should read: one, word. Two, word. Three, word. All the way to twelve or twenty-four, depending on what your wallet showed you.

Double-check what you wrote against the screen. Triple-check. If even one word is wrong, your backup is useless. Take your time.

When you're done, the wallet will probably ask you to confirm the seed phrase by re-entering some of the words. Do that. If you make a mistake, go back and write the seed phrase down again, properly.

Now — where do you put the paper?

Three rules.

One: somewhere fire and water resistant. A small fireproof document bag from any hardware store costs about fifteen dollars and will save your Bitcoin from a house fire. If you're not ready to buy one yet, a sealed plastic ziplock bag inside a metal tin in a closet is a reasonable starting point.

Two: somewhere a thief wouldn't think to look. Not your sock drawer. Not your bedside table. Not in a folder marked "important documents." The point is: if someone broke into your house and searched casually for valuables, they should not find this paper.

Three: somewhere you will remember in five years. This is the hardest one. You don't use your seed phrase often — maybe never. So you have to pick a place memorable enough that future-you can find it without instructions.

A few quick "what NOT to do" notes — we'll cover scams more in lesson ten, but right now:

Never take a photo of your seed phrase. Even "just to have a digital backup." Photos sync. Photos get hacked. Photos are the single most common way Bitcoin gets stolen.

Never type your seed phrase into any website or app — except the wallet that gave it to you. Anyone who asks you to type your seed phrase into anything else is trying to steal your Bitcoin. There are no exceptions to this rule.

Never tell anyone your seed phrase. Not customer support. Not me. Not your brother. Nobody. If you ever need someone's help with your wallet, you can give them everything except the seed phrase.

That's it. Your wallet is set up. Your seed phrase is written down properly. In the next lesson — and this is the differentiator most beginner courses skip — we add a second layer of protection. Something called the 25th word. It's the difference between a wallet that's backed up and a wallet that's actually safe.
