Bitcoin is unforgiving of mistakes

Most losses come from everyday life colliding with a system that expects perfect behaviour from humans.

Collaborative security reduces single points of failure, so your Bitcoin stays safe, accessible, and inheritable when life gets messy. You move from hoping the structure holds to a documented plan your family can follow.

Where are you starting from?

Bitcoin security decisions

Compare your Bitcoin security options

How Bitcoin is secured, documented and passed on matters more over time than most people initially realise. The goal is simple: keep your Bitcoin safe, accessible, and inheritable, without putting everything on one person, one device, or one company.

Solo self-custody

Powerful, but fragile when meaningful Bitcoin depends on one person, one device, one backup, or one memory. In single-signature custody, one compromised seed can expose the whole wallet.

Exchange

Exchanges are useful for buying, selling and settlement. They are not designed to be the permanent security layer for meaningful Bitcoin holdings. Leaving Bitcoin on an exchange concentrates platform dependence: counterparty risk, opaque operations, and seizure or freeze vectors.

Bitcoin ETF

An ETF typically gives you exposure through a brokerage position in a fund; self-custody means you (often with collaborative multisig) control keys to Bitcoin on the network. ETFs rely on brokerage procedures, probate delays, and institutional continuity.

Legal authority alone

Legal authority alone does not recover Bitcoin. A will may name an executor. It rarely prepares that person to act safely with bearer assets under stress.

How it works

How We Help Families Protect Bitcoin Long-Term

  1. Step 1: Set up the vault

    Your vault has three keys. You control one. The Bitcoin Adviser controls one. The vault company, Theya or Unchained, controls the third. Two of the three keys must approve a transaction before the Bitcoin can move. Only you can initiate a transaction.

  2. Step 2: Write the plan

    Your Estate Plan Protocol documents exactly what your heirs need to do to access your Bitcoin. It complements your will. It does not replace the legal instructions that govern asset distribution.

  3. Step 3: Test it with the family

    Most security structures are never tested under failure conditions. We design and rehearse them before they are needed.

Try it: which keys can move the Bitcoin?

Only you can start a transaction. Two of the three keys must approve it before Bitcoin can move. Choose two keys to see how.

0 of 2 required

No keys chosen. Nothing can move.

Theya and Unchained use their company key differently. See how signing works.

The cost of doing nothing

Your family does not just need to know who inherits your Bitcoin

They need to know how to start the right process safely. Families are left improvising: searching for clues, trusting the wrong instructions, or freezing because no one knows where to begin. That is when irreversible mistakes happen.

The Estate Plan Protocol exists to close that gap: not by publishing secrets, but by giving the right people a calm, client specific starting point when a serious life event occurs.

Trust that lets you sleep

“I’m just dropping you a ‘thank you’ note for The Bitcoin Adviser onboarding experience. Taking the initial plunge to move our Bitcoin from an exchange into cold storage seemed like a herculean task at the time, but what came next was the real concern.

Sure, removing the threat of being potentially shafted by bad actors was a relief, but that was quickly replaced by stress. And lots of it. At times, the thought of bearing the sole responsibility for securing the funds for our family legacy was terrifying.

Enter you guys at The Bitcoin Adviser. Setting up our collaborative security multisig arrangement has literally changed our lives for the better. The security we now enjoy in knowing our Bitcoin is safe is in very large part due to your efforts in explaining, guiding and finalising the onboarding process. It was seamless, pain-free and quick. I’m now sleeping like a baby.

Thanks again from the O’Connor clan 🙏”

Knowledge transfer that sticks

“These folks get full marks for service and knowledge transfer. They go beyond establishing a multisig and estate planning for your bitcoin. They will teach you what’s under the hood which will be enhanced if you take the time to educate yourself.

100pc recommended from my perspective. You can undertake their initial 30 minute no cost brief and walk away if you prefer.”
