Hold your own Bitcoin —
and understand every step.

Every guide has a point of view, whether it says so or not. Here is ours, in full, before you read a word of the rest.

• Security is something you learn and practise. There is nothing you can buy that does it for you. No device, no service and no clever arrangement is safe on its own — what actually keeps Bitcoin is a person who understands their own setup and has rehearsed it at least once. That is why this is a course before it is a tool, why every recommendation here shows its working, and why testing a backup is a whole lesson rather than a footnote. It is also why we lean the way we do. Attacks only get cheaper and better, and they are now being automated faster than the advice warning you about them — so the convenient shortcut that is merely risky today gets found at scale tomorrow, and anything standing on nothing but obscurity or good luck is on a clock. We would rather teach you the setup that is still standing in ten years. Simplest that covers you — then one step past it, with nothing left whose single failure takes everything — is what that conviction looks like as arithmetic.
• We hold no keys and sell no device. No affiliate links, no referral codes, no hardware brand of our own — not now, not later. It is the one thing the best-funded guides in this space structurally cannot say, and it is why you can take the device ratings at face value.
• Nothing you own should depend on one thing being fine. One wallet, one seed, one maker — everything resting on that staying fine. When a firmware flaw made weak Coldcard seeds guessable, every wallet drained was exactly that, and the holders who came through untouched had combined something: a passphrase, their own dice throws, or a second maker’s key. It is about combining independent things, not about multisig — one wallet with a passphrase the device never saw already clears it, and three keys from one manufacturer do not. If losing your Bitcoin genuinely wouldn’t change your life, one wallet kept properly is still an honest answer and we say so plainly when we recommend it. Everywhere above that, levelling up is the recommendation.
• Choose the simplest setup that covers you. Not the most impressive setup, and not the one a vendor is selling. More keys and more clever schemes are the single biggest cause of lost Bitcoin, so complexity you don’t fully control is itself a threat. Climb a rung when your situation genuinely outgrows the one you’re on — not because the next one sounds more serious. Where this and the point above collide, the point above wins.
• Every choice trades one risk for another. What makes it harder for a thief to reach your coins usually makes it easier to lock yourself out. There is no arrangement without a downside — only the one whose downsides you picked on purpose. We will always tell you which you’re picking.
• We never ask what you hold, and nothing leaves your browser. No accounts, no analytics, no trackers, ever. Every tool here runs on your own device, and saving anything is a separate choice you make deliberately.
• We publish our conclusions — including the ones that don’t flatter us. When we get something wrong we say so, with a date, rather than quietly editing the page. That is what the change log is for.
• Verify. Don’t trust. Check your backup instead of assuming it. Check the address on the screen instead of trusting the computer. Check the rules yourself, with your own node, instead of taking a company’s word for what’s yours.

All of it comes down to twelve rules — the first lesson of the course, and two minutes to read. Every one of them has a full lesson behind it.
