Why You Should Hold Your Own Bitcoin | BTC Prague 2025 Panel

At the BTC Prague stage, a panel of Bitcoiners — builders, educators, and self-custody advocates — made the case for why holding your own keys isn’t just a technical choice. It’s a statement about freedom, sovereignty, and how much you truly value what’s yours.

Not Your Keys, Not Your Bitcoin

Let’s start with the basics. Self-custody means you are the sole controller of your Bitcoin. No intermediaries, no third parties, no one who can freeze, confiscate, or lose your funds on your behalf. The moment you give someone else your keys, you introduce counterparty risk — and that risk is very real.

I’ve seen it happen. Someone had their coins on an exchange, woke up the next morning, and withdrawals were disabled. The money was gone. That’s the moment most people start learning about self-custody — but it’s too late by then. Think of self-custody like insurance. You only realize you needed it after something goes wrong.

The Risks You Don’t Think About

People often worry about the risks of holding their own keys — losing them, making a mistake during a transfer, or becoming a target. Those risks are real, and you should think about them. But consider what you’re exposed to when someone else holds your keys.

What if the exchange gets hacked? What if it goes bankrupt? What if a court order freezes your account because of a legal dispute that has nothing to do with you? I’ve seen a case where former business partners had their bank accounts frozen years after selling their stake in a company — because of a labor dispute from before they were even involved. The judge froze everything. That can happen to your Bitcoin on an exchange too.

And here’s one most people don’t know about: dormant asset laws. In many countries — and recently in California specifically for Bitcoin — if your exchange account hasn’t been touched in three to five years, the state can legally confiscate those coins. Proving ownership afterward is an uphill bureaucratic battle you may never win.

Your Decision Has to Be an Informed One

I’m not here to tell you there’s one right answer for everyone. What I believe deeply is that your decisions need to be conscious and informed. The worst outcome isn’t losing Bitcoin — it’s losing it and realizing you never truly understood what you were doing or why.

If you decide to keep Bitcoin on an exchange because you’re not confident managing your own keys yet, that’s a choice. But be honest with yourself: you are accepting a lower level of sovereignty. If something goes wrong, you have to be able to look back and say, “I knew the risks and I chose this path.” That’s very different from being blindsided.

Aristotle said that many people are by nature slaves. One way to read that: do you actually value freedom? Because if it’s more convenient to let someone else hold your property, and one day that property disappears — that convenience came at a cost.

Self-Custody Is Easier Than You Think

Here’s the good news: self-custody is not that hard. You don’t need to be a technical wizard. Start with a mobile wallet like Phoenix. Get comfortable. Then move up to a hardware wallet — a dedicated device with a trusted display that shields your keys from the internet-connected world around it.

Back up your seed words. Not on your computer, not as a photo on your phone — on steel plates, offline, somewhere secure. Add a passphrase: a memorable sentence you can recall without writing it down, using words no one could guess. Not your favorite quote from a book you’ve posted about online.

As your stack grows, think about multisig — a setup where multiple wallets need to co-sign a transaction. This protects you against physical attacks too, because no single device gives full access to your funds.

Structure your holdings like you structure your cash. A little on your phone for daily spending. More in a secure hardware wallet for savings. Your long-term family wealth in a properly
