Keep control of your Bitcoin without carrying the risk alone.
The Bitcoin Adviser helps families and long-term holders build client-controlled multisig structures with professional key agency, clear documentation, and continuity support, so their Bitcoin is not dependent on one person, one device, or one point of failure.

The problem with Bitcoin custody is not just theft. It is fragility.
Exchange custody
Convenient, but introduces platform, withdrawal, insolvency, and counterparty risk.
Solo self-custody
Powerful, but fragile when meaningful Bitcoin depends on one person, one device, one backup, or one memory.
Full third-party custody
Simple, but gives up the control that makes Bitcoin different.
Collaborative security
A middle path: client-controlled Bitcoin with professional key agency, documented procedures, and continuity support.
Client-controlled multisig, with professional support around the key structure.
Collaborative security uses a 2-of-3 multisig structure. You hold one key. A technology partner may hold one key. The Bitcoin Adviser may act as one key agent under a documented signing policy.
No single party can move Bitcoin alone. You remain in a client-controlled structure, while the signing model reduces avoidable single points of failure.
No single party can move funds alone. You remain in control. Orange paths show one example quorum: any valid pair of two signatures works.
Control map
| Role | Holds a key? | Can initiate spends? | Can move funds alone? |
|---|---|---|---|
| You | Yes | Yes | No (needs one co-signer) |
| Technology partner (Theya/Unchained) | Yes | No | No (needs one co-signer) |
| The Bitcoin Adviser | Yes | No | No (needs one co-signer) |
You initiate spends; co-signing follows your authorization within the policy. For deeper hardware and device guidance, see Security Centre.
Professional key agency, without custody.
In a collaborative security structure, The Bitcoin Adviser may act as one key agent within a 2-of-3 multisig arrangement.
That means we can support authorised signing workflows, continuity events, and recovery scenarios, but we cannot move client Bitcoin alone, pool assets, trade assets, or act without authorisation.
What this means in practice
- You remain in a client-controlled multisig structure.
- TBA may hold or operate one key under documented policy, where agreed.
- No single party can move funds alone.
- Co-signing follows documented authorisation and verification.
- Key agency supports continuity without becoming custody.
- Full boundaries: Scope, risks & important information.
What The Bitcoin Adviser helps put in place
Custody architecture
Client-controlled 2-of-3 multisig, signer roles, vault partner coordination, and implementation guidance.
Key agency
A documented TBA co-signing role where agreed, with authorisation and verification controls.
Governance documentation
Authorisation maps, role clarity, transaction procedures, review notes, and continuity runbooks.
Continuity planning
Processes for device loss, signer changes, incapacity, death, role turnover, and family handover.
Education for stakeholders
Clear explanations for clients, beneficiaries, trustees, advisers, and family members. Deeper workshops and pathways: Education & Advisory.
Ongoing review
Periodic checks so keys, devices, documents, advisers, and family roles do not drift over time.
Built for the moments when ordinary self-custody breaks down
- A device is lost or damaged.
- A key holder becomes unavailable.
- A signer changes phone, location, or role.
- A spouse or beneficiary needs guidance.
- A transaction request looks unusual.
- A family office, trustee, or adviser needs a clear process.
- A platform needs to be migrated.
- A plan has not been reviewed in years.
Collaborative security does not remove every risk. It reduces avoidable single points of failure and gives clients a documented process when life changes.

Inheritance is where custody structure gets tested.
Legal authority alone does not recover Bitcoin. Collaborative security gives families a structure of roles, signers, documentation, and education that can support an Estate Plan Protocol.

"The biggest challenge I needed to overcome in getting comfortable with self-custody of Bitcoin was the security risk. The Bitcoin Adviser sorts that in one fell swoop. Having my own personal contact to boot puts icing on the cake!"
"Self custodying my BTC with TBA's services has allowed me to feel safe for my own retirement and my family's future. Pete and Andy are the most generous of people with their time and care, always accessible."
