Bitcoin Ownership Is Easy.
Survivable Control Is Where It Breaks.
Family offices are built to preserve wealth across people, entities, jurisdictions, and generations. Bitcoin introduces a different requirement: direct technical control over a bearer asset, with no institutional reset button.
The Bitcoin Adviser helps family offices build the control layer: collaborative security, documented authority, key-agent support, inheritance continuity, and practical readiness for the people who may need to act under pressure.
Led by Peter Dunworth, a family office operator with Bitcoin custody experience since 2016. Background is detailed in Led by Peter Dunworth below.

Continuity is the point: trustee transitions, incapacity, and operational turnover are where governance fails if the control layer is undocumented. Related: Continuity · Estate Planning & Inheritance · Bitcoin Executor Support.
Important
This is technical education and support for self-custody Bitcoin solutions only: not financial, investment, tax, or legal advice. Bitcoin carries high risks including total loss.
Why Bitcoin Changes the Operating Model
Bitcoin is the first globally liquid bearer asset that can be controlled directly by individuals and families without institutional intermediaries.
Traditional family office assets rely on layers of institutional dependency: banks, brokers, custodians, registrars, trustees, fund administrators, courts, and jurisdictions. Bitcoin changes that model. It can reduce reliance on institutional control, but only if the family can manage private key control, succession, execution, and governance correctly.
The same stresses reach high-net-worth individuals, multi-generational families, trustees and fiduciaries, and long-horizon structures (retirement planning context →). The moment Bitcoin depends on more than one person, device, or event, control becomes the problem.
Custody Is Not Enough
Traditional wealth stacks assume custody plus advice covers the asset. Bitcoin breaks that assumption when execution and continuity cannot follow authority on paper.
Custody answers where the asset sits. Control answers who can act.
| Layer | Traditional System | Bitcoin Reality |
|---|---|---|
| Legal | Defines authority | Still required |
| Tax | Reporting | Still required |
| Investment | Allocation | Still required |
| Custody | Safekeeping | Not sufficient |
| Control | Often implicit | Critical and often missing |
The Bitcoin Adviser operates in this missing layer: control. We do not sell custody as a product. We help families and offices run Bitcoin as a governed sleeve: clear roles, documented approvals, and an Estate Plan Protocol so heirs and fiduciaries are not left guessing when stress hits.
Authority on paper is meaningless without the ability to execute.
The Four Family Office Bitcoin Failure Modes
For family offices, Bitcoin usually does not fail at the allocation memo. It fails at the control layer, when authority cannot execute. These are the four patterns we see most often, and each links to a deeper doctrine page.
Legal authority without technical control
Trustees hold authority on paper but cannot move Bitcoin. A court order cannot reset a blockchain. Why authority is not control →
The smartest-person failure mode
One technical family member becomes the undocumented operating system, and a single point of failure. The expert-dependent trap →
Incapacity before death
A living principal cannot sign, explain, or recover access after a stroke, dementia, or detention. Plan for living failure →
Instructions mistaken for a plan
Static documents fail when people, devices, or circumstances change. Why instructions are not a plan →

TBA's Control-Layer Model
The Bitcoin Adviser does not replace your legal, tax, or investment advisers. We sit in the operational control layer: the part of the system that determines whether Bitcoin can actually be secured, moved, recovered, and inherited when required. No one person should be able to move Bitcoin alone, approvals should match how you already govern, and recovery has to work when the usual people are unavailable.
How the stack runs
Execution control
Authorized co-signing in your multisig. The family holds keys; we are not a custodian.
Operational capability
What people actually do under pressure, reviewed as stakeholders change.
Investment Committee-Ready Outputs
You are not buying a one-off setup. You are implementing a repeatable control system your IC can actually adopt: something heirs and trustees can follow when the moment is hard, not only when the slide deck is fresh.
Clear objectives, role responsibilities, and governance gates so Bitcoin is managed as a real sleeve, not an orphaned asset.
Phasing approach, clear order of steps, and stakeholder alignment, built to reduce timing stress and internal friction.
Quorum approvals, signing workflow, change-control, and verification steps, documented so responsibility stays unambiguous.
Bitcoin inheritance continuity: trustees/executors get an actionable playbook, not a technical puzzle.
A step-by-step signing manual for non-technical fiduciaries. Demonstrates to the Investment Committee that they are buying a repeatable system, not just a one-time setup. Unlike paper instructions that fail under stress, these are functional protocols with professional support. Learn why instructions alone aren't enough →

Working Session: Map Your Control Model
This is not a generic consultation. It is a working session to map your control model with Peter: who holds responsibility, how signing and continuity work, and how Collaborative Security, Key Agent support, and the Estate Plan Protocol fit together.
Before proceeding, review our Scope & Risks.
Come prepared to align principals, trustees, and advisors. Review the Generational Bitcoin Playbook and note stakeholders, governance expectations, and your current custody setup.
Working sessions are scheduled in advance; calendar availability varies week to week. If you need a specific timeframe, email often secures a slot faster than the calendar alone.

Common Family Office Questions
Is this “custody” or advisory?
Our focus is the Bitcoin control layer: governance-controlled implementation, documented controls, inheritance continuity, and ongoing support.
Custody answers who holds the asset; we address who can execute under policy when it matters. Key Agent support is execution control within your structure, not pooled custody. Read Key Agent, not custodian and our Scope, Risks & Important Information.
How do you prevent one person from becoming the point of failure?
Collaborative security removes unilateral control.
Roles and approvals are mapped to your governance model, with documented authorization workflows and recovery steps that remain valid even when key people change.
What happens if a trustee/executor needs to act during incapacity or death?
This is precisely what the Estate Plan Protocol is built for: clear instructions, stakeholder alignment, and practical readiness, so fiduciaries can execute without technical paralysis.
Do you support US and other jurisdictions?
Yes.
Security is global; risk is jurisdictional. We coordinate with your legal and tax advisors to ensure governance and documentation match your jurisdictional requirements.
What if our Trustee doesn't know how to use a hardware wallet?
This is precisely why we provide Fiduciary Runbooks: step-by-step signing manuals for non-technical fiduciaries.
Our "Guided Handover" and "MVK" (Minimum Viable Knowledge) approach means Trustees receive clear, actionable procedures, not technical training requirements. Collaborative security removes technical barriers: fiduciaries work with our professional team during recovery events, ensuring they're never alone. The Fiduciary Runbooks demonstrate to your Investment Committee that you're buying a repeatable system, not a one-time setup that depends on technical expertise.
