Bitcoin for Family Wealth | Solidus Wealth

Introduction

Families with significant wealth—for example, above US$ 100,000—are increasingly incorporating Bitcoin into their long-term investment strategies. Bitcoin has consolidated itself as a scarce digital store of value, attractive in scenarios of high inflation and excess liquidity in the traditional financial system.

Many adherents view Bitcoin not as a short-term speculative bet but as a solid hedge to protect wealth over the years. In this context, the need arises to plan multigenerational Bitcoin allocations—that is, structuring the cryptocurrency’s role in the family’s wealth so it benefits not only current investors but also their heirs and future generations.

“We learned the hard way in 2022 that entrusting bitcoins to intermediaries can be disastrous: several crypto lending and yield providers—including major names like BlockFi, Voyager, and Celsius—became insolvent and collapsed, leaving clients with losses.”

Moreover, keeping your assets with exchanges or third-party custodians runs counter to the sector’s fundamental principle: “Not your keys, not your coins.” In other words, if you don’t hold the private keys, you don’t truly own your bitcoins. Funds kept on exchanges carry the risk of total loss due to custody failures or legal issues.

Therefore, the key to a conservative Bitcoin strategy lies in secure self-custody and robust key-protection practices—topics we cover below. Fortunately, there are now specialized services that help high-net-worth investors on this journey, combining Bitcoin expertise with traditional wealth-management practices.

Bitcoin as a Pillar of Family Wealth

For families with a conservative profile and a focus on capital preservation, including Bitcoin in the portfolio may seem counterintuitive at first glance given the asset’s apparent volatility. However, it’s important to distinguish the short-term view from the long-term view.

Over longer horizons (5, 10, 20 years or more), Bitcoin has shown a historical trend of significant appreciation, driven by its programmed scarcity and growing adoption. Large investors and companies have been accumulating bitcoins with a long-term mindset—an emblematic case was Méliuz, the first Brazilian listed company to adopt Bitcoin in its strategic treasury.

From a wealth-protection standpoint, Bitcoin can act as “digital gold,” shielding family wealth from fiat-currency debasement over decades. Unlike stocks or real estate, Bitcoin does not generate cash flow or dividends; its proposition is to be the hardest, most inflation-resistant asset—hence many enthusiasts argue that “Bitcoin isn’t an investment; it’s a hedge.”

        Essential precautions when using Bitcoin as a family-wealth pillar:
        
            Avoid unnecessary risks: In family-wealth management, capital preservation is the priority. Income-generating strategies with Bitcoin (such as lending it to third parties for interest or engaging in complex DeFi) should be approached with extreme caution—or avoided.
          
            Plan liquidity for short-term needs: Even if the family decides to allocate a substantial portion (e.g., >90%) of wealth to Bitcoin, it’s wise to keep a liquidity reserve in fiat or other reasonably liquid assets to cover ongoing expenses, emergencies, and taxes.
          
            Rely on professional advice: Securing large Bitcoin sums requires technical know-how—from choosing hardware wallets and offline storage setups to implementing backup protocols.

In short, with the right approach, Bitcoin can indeed play a central, conservative role in a family’s wealth as a safe harbor of value. What matters is that this allocation comes with impeccable technical execution aligned with long-term objectives—something Solidus Wealth is prepared to deliver through its blend of Security, Strategy, Education, and Trust.

Building a Bitcoinized Future (Allocation > 90% in BTC)

Many Bitcoiners believe in a scenario of bitcoinization, in which the cryptocurrency would become the dominant global money, supplanting fiat currencies as the primary medium of exchange and store of value. For families who share this conviction, it makes sense to consider allocating more than 90% of total wealth to Bitcoin, aiming to maximize exposure to what they see as the money of the future.

This is, undoubtedly, a bold strategy compared to traditional recommendations (where non-traditional assets usually occupy much smaller percentages of the portfolio). However, from the standpoint of those betting on a bitcoinized future, a high percentage can be rational: if Bitcoin does in fact absorb a large share of the global economy’s value, current holders would be proportionally rewarded in the preservation and multiplication of wealth.

Adopting a “Bitcoin-maximalist” stance in allocation brings advantages and challenges. Among the advantages is simplicity: concentrating in Bitcoin reduces the complexity of diversifying across multiple assets, and historically “allocating 100% to BTC simplifies decision-making and helps build confidence in long-term investing.”

Advantages

Simplicity in wealth management
Alignment with global technological adoption
Maximum exposure to upside potential

Challenges

Short-term volatility can test conviction
Need for ongoing family education
Expectation management across generations

“Another sensible measure when pursuing a hyperbitcoinized future is to establish clear family-governance rules for this allocation. This includes defining which decisions require consensus (for example, selling a significant share of the bitcoins might require agreement among key family members) and what exit mechanisms exist if an heir disagrees with the strategy in the future.”

Wealthy families often formalize family offices or family councils to manage assets; in Bitcoin’s case, this may involve anything from internal policies to specific legal structures (such as trusts or special-purpose entities) to house the bitcoins and facilitate multi-generational management.

Long-Term Estate Planning

When the investment horizon is multi-generational, it’s not enough to buy and hold bitcoins—you must ensure they actually reach the next generations safely and lawfully. Estate planning involving Bitcoin presents unique challenges: on the one hand, there are legal and tax aspects (after all, despite being decentralized, Bitcoin is considered property for inheritance purposes and may be subject to estate or inheritance taxes); on the other hand, there are technical aspects regarding access to private keys and asset custody.

From a legal perspective, the first recommendation is to clearly include Bitcoin assets in the inventory and will. Although Bitcoin has no specific inheritance regulation, it is treated as a digital asset subject to inheritance. As with any other asset, if you own it at the time of death, it will pass to your heirs according to your will’s provisions (or default succession law if there is no will).

Lack of proper planning can result in major headaches for heirs—lengthy court proceedings, family disputes, and even irreversible loss of assets if no one knows how to access them. It is therefore essential to consult a specialist in family and inheritance law—ideally familiar with digital assets—to structure documents such as wills, living wills, or even trusts.

Approaches to Bitcoin estate planning:

In-life access instructions

The wealth holder can choose to gradually pass on knowledge to heirs. For example, teach Bitcoin fundamentals, demonstrate small transactions in practice (which can be done in a controlled environment—as suggested in Solidus’s secure onboarding sessions—using test amounts for familiarity), and even partially share where and how keys are stored. This gradual transfer of responsibility tends to better prepare successors.

Instruction letter and secure storage

Another practice is to leave a letter or detailed documentation in a secure vault (physical or digital) containing wallet-recovery information (seed phrases, hardware-wallet PINs, location of Shamir shards, etc.), along with step-by-step instructions. This documentation must be kept up to date, and a trusted person (e.g., the executor or an attorney) should know it exists and how to access it when needed.

Ongoing training and education

Often, the patriarchs or matriarchs accumulate deep Bitcoin knowledge over the years, but the children/heirs do not follow at the same depth. This creates the risk that, in the absence of the main enthusiast, heirs may not grasp the value of what they received and make hasty decisions (such as selling all the bitcoins at the first opportunity for lack of understanding of long-term potential). Ideally, engage successors now: enroll them in courses, involve them in reading on Bitcoin and economics, and bring them into meetings with advisors.

In short, planning the succession of Bitcoin wealth requires combining traditional legal tools (wills, trusts, etc.) with modern technical strategies (key delivery, multisig, documentation) and heir education. With these fronts well aligned, you avoid the nightmare of seeing an entire legacy dissipate due to lack of access or poorly informed decisions.

Secure Custody: Multisig Wallets

When it comes to keeping bitcoins safe for decades and across generations, few solutions compare to custody in multi-signature (multisig) wallets. In this arrangement, coins are protected by several distinct private keys, requiring a quorum (minimum number) of signatures to authorize any movement. For example, in a 2-of-3 scheme, three keys are generated and stored separately, and at least two of them must sign a transaction for it to be valid.

This structure brings vital benefits for family wealth:

Redundancy against loss

If one key is lost (e.g., a device is misplaced or a custodian dies), there are still enough remaining keys to move funds. Thus, the single-point-of-failure risk is mitigated. In contrast, a simple single-sig wallet relies on one key; if it is lost or destroyed without backup, the bitcoins are unrecoverable.

Protection against theft and coercion

A malicious attacker would need to compromise multiple keys stored in different locations to steal the bitcoins—exponentially harder than stealing a single key. This also increases personal safety: it reduces the incentive for physical threats (the “$5 wrench attack”), since even coercing one person into surrendering their key would not allow thieves to spend funds without the other parties.

Enables planned succession

As experts highlight, multi-signature wallets “can be an effective alternative for including Bitcoin in estate planning and protecting family wealth.” Returning to the 2-of-3 example: imagine the patriarch holds the first key, the primary heir holds the second, and a trusted institution (such as Solidus Wealth itself) holds the third.

Expert collaboration

A growingly recommended model is collaborative multisig, in which one of the keys is held by a trusted specialist. This person or Solidus Wealth cannot unilaterally spend the funds, but can assist with co-management and, crucially, guide the heirs in the future.

Professional Implementation

Implementing an ideal multisig wallet requires technical expertise and planning. You must decide the number of keys and quorum (2 of 3? 3 of 5? etc.), generate each key in a secure environment (preferably 100% offline to avoid the risk of hackers intercepting seed phrases), and distribute copies across geographically separate locations (e.g., storing devices or backups in secure vaults in different countries, mitigating natural-disaster or regional-instability risks).

Solidus Wealth is highly active in this area, offering geographically distributed multisig implementation, with key generation in secure environments, signing across different continents, and even the use of schemes such as Shamir’s Secret Sharing for maximum resilience. This kind of professional solution ensures the family gets the most from multisig technology without incurring operational errors.

In summary, multisig custody represents the state of the art in security for large Bitcoin fortunes. It simultaneously meets the demand for extreme protection and the need for planned accessibility by heirs. Families that adopt multisig—with proper advice—can rest assured their bitcoins will be as safe as possible against misfortune, while also not being lost in generational transitions.

Conclusion

Structuring Bitcoin investments to span generations is a multidisciplinary challenge—it involves strategic vision, investment discipline, cutting-edge technical solutions, and sensitivity in family planning. Recapping the pillars covered in this report:

Long-Term Conviction

The decision to allocate a significant (sometimes majority, >90%) share of wealth to Bitcoin must be grounded in conviction about its role as the money of the future and a superior store of value.

Preservation and Conservatism

Even with a high allocation, the approach remains conservative in avoiding unnecessary risks. No gambling with risky derivatives, lending, or opaque strategies—the focus is buy, custody, and hold.

Estate and Legal Planning

Integrating Bitcoin into the family’s estate plan ensures an orderly, uneventful transfer of assets. Up-to-date wills, potential fiduciary structures (trusts, holding companies), and transparent communication to heirs about the existence of these assets are basic steps.

Family Education and Alignment

Wealth only survives intact across generations if successors are prepared to assume it. Educating heirs on what Bitcoin is, why the family invested in it, and how to handle it safely is just as important as the wallets’ technical setup.

In each of these pillars, specialized support makes all the difference. Solidus Wealth positions itself precisely as a comprehensive partner for families who want to follow this path. From the initial strategy phase—aligning Bitcoin allocation with the family’s risk profile and objectives—to execution and maintenance (wallet setup, security audits, user training, ongoing technical support), the Solidus team provides dedicated know-how and guidance.

In a future possibly dominated by Bitcoin, being prepared today is the best gift one generation can leave to the next. With a well-structured strategy, top-tier security, and professional guidance, a family’s Bitcoin wealth can flourish over decades—regardless of changes in currencies, financial systems, or borders.
