When a business partner dies and the company holds Bitcoin, three crises hit simultaneously: the deceased partner's heirs inherit an interest in a volatile asset they may not want, the surviving partners lack liquidity to buy them out, and no one agrees on what 150 BTC is "worth" when the price moved 8% between the death certificate and the first attorney call. Standard buy-sell agreements were designed for businesses with predictable revenue and stable balance sheets. Bitcoin businesses have neither. This guide covers the legal structures, valuation mechanics, insurance strategies, and operational procedures that prevent a partner's death from destroying the company — and the family wealth embedded in it.
Most business partnerships operate on a dangerous assumption: that both partners will be around tomorrow. Statistically, that's usually true — until it isn't. And when it isn't, the absence of a succession plan transforms a personal tragedy into a business catastrophe.
Here's what happens by default when a business partner dies without a buy-sell agreement in place: the deceased partner's ownership interest passes to their heirs through probate or a revocable trust. Those heirs — typically a spouse and children — become the new co-owners of the business. They have the same economic rights as the deceased partner: profit distributions, voting rights on major decisions, access to financial records, and a claim on the company's assets including any Bitcoin on the balance sheet.
The surviving partner now has business partners they didn't choose, who may have no interest in the business, no understanding of its operations, and no alignment with its strategy. The heirs want cash. The surviving partner wants to keep running the company. These goals are fundamentally incompatible without a pre-arranged exit mechanism.
Now add Bitcoin to this scenario, and every problem compounds:
The deadly gap is the distance between "we should set this up eventually" and the phone call that starts with "I'm sorry to inform you." Every week that gap remains open is a week the entire business is one cardiac event, one car accident, one diagnosis away from an outcome no one intended. As we detail in our comprehensive Bitcoin estate planning guide, the time to plan is when nothing is wrong — because by the time something is wrong, the planning window has closed.
A buy-sell agreement is the contractual mechanism that prevents every disaster described above. It's a binding agreement between business partners (and sometimes the entity itself) that governs what happens to a partner's ownership interest upon certain triggering events: death, disability, divorce, bankruptcy, voluntary departure, or retirement.
The core function is simple: when a trigger event occurs, the surviving partners have the right and obligation to purchase the departing partner's interest at a price determined by the agreement, using a funding mechanism specified in the agreement. The departing partner (or their estate) receives cash. The surviving partners retain control of the business. No one ends up in an involuntary partnership with people they didn't choose.
Three primary structures exist, and each interacts differently with Bitcoin treasury holdings.
Each partner personally agrees to purchase the deceased partner's interest. In a three-partner Bitcoin mining company, Partner A and Partner B each buy half of deceased Partner C's interest.
Advantages for Bitcoin businesses: The purchasing partners receive a stepped-up basis in the acquired interest — critical when the underlying Bitcoin has appreciated significantly since the partnership acquired it. The surviving partners' outside basis increases by the amount paid, which can reduce future capital gains on Bitcoin dispositions. For entities holding low-basis Bitcoin, this advantage alone can be worth hundreds of thousands in future tax savings.
Disadvantages: In a multi-partner Bitcoin business, the insurance and funding logistics become complex. With three partners, you need six separate life insurance policies (each partner owns a policy on each other partner). With four partners, you need twelve. The premium burden falls on individual partners, not the entity — and partners in a Bitcoin mining operation may have wildly different personal liquidity profiles.
The business entity itself purchases the deceased partner's interest. The LLC or partnership buys back the membership interest using entity funds — which, in a Bitcoin business, likely means selling BTC to generate the cash needed for the buyout.
Advantages for Bitcoin businesses: Simpler structure — the entity owns one policy on each partner. Only three policies for a three-partner company instead of six. The entity controls the timing and funding.
Disadvantages: No basis step-up for surviving partners. The entity's inside basis in the Bitcoin treasury remains unchanged. If the partnership holds 150 BTC with a basis of $15,000 per coin and BTC is trading at $100,000, the surviving partners inherit the entity's low-basis Bitcoin problem. Additionally, if the entity must sell BTC to fund the redemption, it triggers taxable gains at the entity level — compounding the cost of the buyout.
This is the critical distinction most business attorneys miss when drafting buy-sell agreements for Bitcoin companies: an entity redemption that requires selling appreciated Bitcoin to fund the buyout creates a tax event that erodes the very treasury the surviving partners are trying to preserve.
The entity has the first option to redeem the deceased partner's interest. If it declines (or can only partially redeem), the surviving partners cross-purchase the remainder. This structure provides maximum flexibility for Bitcoin businesses because it allows the entity to evaluate whether selling BTC at current prices is advantageous or whether the surviving partners should fund the purchase personally — perhaps using life insurance proceeds held outside the entity.
For most Bitcoin partnerships, the wait-and-see structure is optimal. It preserves optionality in a volatile asset environment and allows the surviving partners to make the cross-purchase vs. redemption decision based on market conditions at the time of death — not conditions that existed when the agreement was drafted three years earlier. For more on how entity structure affects succession planning broadly, see our Bitcoin business succession planning guide.
A standard buy-sell agreement drafted for a traditional business — a dental practice, a real estate portfolio, a consulting firm — fails catastrophically when applied to a Bitcoin-holding entity. The asset characteristics of Bitcoin require provisions that most business attorneys have never drafted because the problems didn't exist before Bitcoin became a corporate treasury asset.
The single most contested element in any bitcoin buy-sell agreement is valuation. Bitcoin trades 24/7/365 on dozens of exchanges in multiple currencies. There is no "closing price" in the traditional sense. The agreement must specify:
A partner who suffers a medical emergency may be incapacitated for days or weeks before death. During that window, their multisig key is inaccessible. The buy-sell agreement should address who has authority to access the incapacitated partner's key material — and under what conditions — before the death trigger even fires. This is a security problem as much as a legal one: an uncontrolled hardware wallet passing through hospital property rooms and eventually probate court is a custody vulnerability.
When one keyholder in a 2-of-3 multisig dies, the quorum doesn't change — but the security model does. The two surviving keyholders can move funds without the deceased's key. This means the surviving partners have unilateral control of the treasury at the exact moment the estate has a competing economic claim. The buy-sell agreement should mandate: (a) immediate notification to the estate's personal representative, (b) an independent audit of treasury balances within 72 hours, and (c) a freeze on non-operational BTC movements until the buyout closes or a successor keyholder is designated.
Partners in a Bitcoin business often hold BTC both inside the entity and personally. The buy-sell agreement governs only the entity interest — but the valuation of that interest depends on where the BTC sits. If a partner contributed personal BTC to the entity's treasury, was it a capital contribution (increasing their capital account) or a loan? If the entity's BTC was purchased with entity funds, it's clearly a partnership asset. If a partner "lent" BTC to the entity for operational use but retained personal ownership, the buy-sell should not include that BTC in the entity valuation. These distinctions must be documented clearly in the operating agreement and reconciled annually.
Life insurance is the engine that funds buy-sell agreements. Without it, the surviving partners must either liquidate Bitcoin treasury (triggering gains), take on debt (introducing leverage into an already volatile business), or pay the estate over time (creating a creditor relationship with the deceased partner's heirs that poisons the business). None of these outcomes is acceptable for a well-structured Bitcoin business.
The optimal structure uses an Irrevocable Life Insurance Trust (ILIT) to own the policies. Each partner creates an ILIT. The ILIT purchases a life insurance policy on the partner's life. When the partner dies, the ILIT receives the death benefit — outside the deceased partner's taxable estate. The ILIT then uses the proceeds to purchase the deceased partner's business interest from the estate (in a cross-purchase arrangement) or lends the proceeds to the surviving partners for that purpose.
For Bitcoin business owners whose combined business interest and personal Bitcoin holdings may approach or exceed the federal estate tax exemption — currently $13.99 million per person under the 2026 framework — keeping insurance proceeds outside the estate is not optional. It's essential. A partner with a $5 million business interest and $12 million in personal Bitcoin is already over the exemption. Adding a $5 million insurance death benefit to the estate pushes the tax exposure higher. The ILIT eliminates this problem entirely.
Bitcoin business partners can fund ILIT premiums by taking distributions from the partnership, selling small amounts of BTC personally, or using partnership income from mining operations. The critical constraint: annual gifts to the ILIT must stay within the $19,000 annual gift exclusion per beneficiary (2026) to avoid consuming lifetime exemption. With Crummey withdrawal rights and multiple beneficiaries, a well-designed ILIT can absorb $100,000+ in annual premiums without gift tax consequences.
Beyond buy-sell funding, Bitcoin businesses need key man (key person) insurance to cover the operational disruption of losing a critical partner. If one partner manages all custody operations, mining equipment maintenance, or energy contract negotiations, their death creates an immediate operational gap that costs real money to fill — recruiting a replacement, training them, potentially renegotiating contracts. Key man insurance provides a lump sum to the entity to cover these transition costs, separate from the buy-sell buyout.
The key man policy should be owned by the entity (not an ILIT) because the proceeds fund operational needs, not a buyout. Size the policy at 2-3x the estimated transition cost — typically $500,000 to $2 million for a significant Bitcoin operation.
The insurance amount should be calibrated to the buy-sell price — which means it needs periodic adjustment as BTC appreciates. A policy sized for a $3 million buyout when BTC was $40,000 may be woefully inadequate when the same partnership interest is worth $8 million at $100,000 per coin. Build an annual review requirement into the buy-sell agreement: every January, partners recalculate the estimated buyout value and adjust coverage if the gap exceeds 15%.
Bitcoin mining partnerships present the most complex bitcoin business partner death estate planning scenario because the business contains at least four distinct asset categories, each requiring different valuation and succession approaches.
Depreciable tangible personal property. Valued at fair market value — which for used ASICs depends on hash rate efficiency, age, condition, and the current BTC price (which determines profitability and therefore demand for used machines). A fleet of S19 XPs has a different value at $100,000 BTC than at $40,000 BTC because the machines' profitability — and therefore resale value — is price-dependent. At death, who controls the mining equipment? If it's located at a hosted facility, the hosting contract determines physical access. If the deceased partner was the named contact on the hosting agreement, the surviving partner may need to renegotiate access.
Below-market power purchase agreements are often the most valuable asset in a mining operation — and the hardest to value. A 5-year contract for power at $0.04/kWh when market rates are $0.08/kWh has substantial value, but it may contain assignment restrictions or change-of-control provisions that limit transferability. The buy-sell agreement must address whether energy contracts are valued at their intrinsic value (the spread between contract and market rates times expected consumption) or at a transfer-restricted discount.
The wallet receiving block rewards is a business asset. Its private key — whether held in a hardware wallet, a multisig configuration, or a custodial arrangement with the mining pool — must be explicitly addressed in the partnership agreement. Who controls the wallet receiving newly mined Bitcoin? If the deceased partner was the sole custodian of the mining payout wallet, block rewards generated after their death may be inaccessible until probate resolves key access. The partnership agreement should mandate that mining payout wallets use multisig custody with at least two partners as keyholders, and that pool payout addresses are documented in a secure location accessible to all partners.
The Bitcoin held on the entity's balance sheet — mined and accumulated over time. This is the simplest to value (market price times quantity) but the most tax-complex to distribute, because the basis of mined Bitcoin is the fair market value on the date it was mined. A treasury of 150 BTC mined over three years has 150 different basis lots, each tied to the BTC price on the day that coin was mined. Tracking and allocating these basis lots in a buy-sell context requires detailed mining records.
Mining Partnership Due Diligence
If you're evaluating a mining partnership — or structuring one — custody, key management, and operational due diligence are non-negotiable. The 36-question framework covers everything from hash rate verification to wallet custody protocols to hosting contract assignment clauses.

Bitcoin mining creates unique tax advantages — bonus depreciation on equipment, operational expense deductions, and strategic timing of BTC disposition. These advantages compound when structured correctly within a partnership. If your business involves mining, understanding the tax mechanics is foundational to every succession decision.
Get the Bitcoin Mining Tax Strategy Resource →When a business holds Bitcoin on its balance sheet, the total enterprise value is the sum of two components: the value of the ongoing business operations and the value of the Bitcoin treasury. These components behave differently, are valued differently, and create different tax consequences — and most business appraisers treat them incorrectly.
The value of the business as a going concern, excluding the Bitcoin treasury: revenue streams, client relationships, intellectual property, equipment, energy contracts, operational capacity. Valued using standard business valuation methods — discounted cash flow, comparable transactions, or capitalized earnings. For a mining operation, this is the present value of future mining revenue based on projected difficulty, halving schedule, and energy costs.
The market value of BTC held by the entity. In theory, this is simply quantity times spot price. In practice, several adjustments may apply: a discount for the embedded capital gains tax liability (if the entity must sell BTC to distribute value), a discount for lack of marketability (if the BTC is held in a complex custody arrangement), and potentially a control premium or minority discount depending on the partner's ownership percentage. See our Bitcoin valuation discounts guide for the full analytical framework.
For estate tax purposes, the IRS values the deceased partner's interest at fair market value on the date of death under IRC §2031. If the business has a buy-sell agreement that sets the price, the IRS will respect that price — but only if the agreement meets the requirements of IRC §2703: the price must be a bona fide business arrangement, not a device to transfer property to family members for less than full consideration, and the terms must be comparable to those in arm's-length transactions.
For Bitcoin businesses, §2703 creates a specific risk: if the buy-sell formula produces a price significantly below the FMV of the Bitcoin treasury (perhaps due to aggressive discounts or a stale valuation formula), the IRS may disregard the buy-sell price and value the interest at full FMV for estate tax purposes — while the estate still receives only the buy-sell price in cash. The estate pays tax on value it never received. This is the worst possible outcome, and it's entirely preventable with proper drafting that produces a defensible, arm's-length equivalent price.
The choice of entity structure determines who controls the Bitcoin, what transfers at death, and how the buy-sell mechanism operates. Each structure creates different outcomes for the surviving partners and the deceased's estate.
The most common structure for Bitcoin businesses and the most flexible for succession planning. The LLC — not the individual members — owns the Bitcoin. At a member's death, the membership interest (not the Bitcoin itself) transfers to the estate. The surviving members continue to control the entity's assets, including BTC custody, through the operating agreement's management provisions.
The operating agreement is the critical document. It should address: who serves as manager if the managing member dies, whether a deceased member's interest converts from a managing to a non-managing interest, what approval thresholds apply to BTC transactions (unanimity? majority?), and how key management responsibilities transfer. For Bitcoin family limited partnerships and LLCs, these provisions interact with broader family wealth transfer strategies.
In a general partnership, all partners have management authority — including authority over Bitcoin custody. At a partner's death, the partnership may dissolve by operation of law (depending on state statute) unless the partnership agreement provides for continuation. The surviving general partner controls operations, but the deceased partner's estate has a claim on partnership assets including BTC.
Limited partnerships offer better separation: the general partner controls operations and BTC custody, while limited partners hold economic interests without management authority. At a limited partner's death, only the limited partnership interest transfers — the general partner retains custody control. This structure is particularly useful for Bitcoin businesses with passive investors alongside active operators.
The corporation owns the Bitcoin as a corporate treasury asset. At a shareholder's death, stock transfers — not Bitcoin. The surviving shareholders and corporate officers retain full control of the Bitcoin treasury through the board of directors and corporate governance documents. The simplicity is attractive, but the tax treatment is not: C-corporations face double taxation on BTC gains (corporate tax on the gain, then shareholder tax on dividends), and S-corporations have restrictions on shareholder types that may complicate estate planning (trusts must qualify as S-corp eligible shareholders).
For most Bitcoin business partnerships, the LLC taxed as a partnership offers the best combination of liability protection, tax efficiency, and succession flexibility. The operating agreement provides the customization necessary for Bitcoin-specific provisions that corporate bylaws typically can't accommodate.
Key management succession is the operational heart of bitcoin business partner death estate planning. Legal documents mean nothing if no one can access the Bitcoin when a partner dies. The technical implementation must be specified in the operating agreement with the same precision as the financial terms.
The recommended custody model for a two- or three-partner Bitcoin business: a 2-of-3 multisig where each key is held by a different party. In a two-partner business, the third key is held by a neutral third party — an attorney, a corporate trust company, or a specialized digital asset custodian. In a three-partner business, each partner holds one key.
When one keyholder dies, the remaining two keyholders can still move funds (2-of-3 threshold is met). This is by design — it prevents a partner's death from freezing the treasury. But it also means the surviving partners have unilateral control at the moment the estate has a competing economic claim, which is why the buy-sell agreement must include treasury audit and freeze provisions as described above.
Each partner designates a successor keyholder in the operating agreement. The successor's role is temporary and limited: participate in the key rotation ceremony after a partner's death, then relinquish the key once the new multisig is established. The ideal successor keyholder is:
The operating agreement should specify a step-by-step protocol:
This protocol must be documented, practiced (via annual drills), and updated whenever a partner changes their successor designation. A trust protector can serve as a neutral third party with authority to facilitate access transitions during the succession process.
Death is straightforward in one respect: it's a definitive event. Incapacitation is far worse for Bitcoin business partnerships. A partner who suffers a severe stroke, traumatic brain injury, or degenerative cognitive decline is neither dead (triggering the buy-sell) nor capable of fulfilling their management obligations. They're a zombie partner — present on the cap table but absent from operations.
A standard durable power of attorney may not cover digital asset management. The agent named in the POA needs explicit authority to:
Without this explicit authority, the surviving partners face a nightmare: the incapacitated partner's agent (often a spouse or adult child with no crypto experience) holds a multisig key they don't know how to use, can't participate in operational decisions, and may not even know the partnership holds Bitcoin.
The buy-sell agreement should define disability as a separate trigger event with its own terms. Standard practice: if a partner is unable to perform their material duties for 90 consecutive days (or 120 days in any 12-month period), the disability buyout provision activates. Two independent physicians must certify the disability. The valuation methodology mirrors the death trigger, but the funding mechanism differs — disability insurance replaces life insurance as the primary source, and the payout timeline is typically longer (24-36 monthly installments rather than a lump sum).
Within 48 hours of a partner's incapacitation being medically confirmed, the partner's designated POA agent must participate in a key rotation ceremony to transfer the incapacitated partner's signing authority to a successor. This protects the treasury from the security vulnerability of an uncontrolled key. The disability provision should also specify a co-signer arrangement: if the incapacitated partner was a required signatory on exchange accounts, the surviving partner gains temporary signatory authority during the disability period.
The tax treatment of a partner buyout is where most of the economic value is won or lost. Structuring the buyout correctly can save the surviving partners and the estate hundreds of thousands of dollars. Structuring it incorrectly can create tax liabilities that make the buyout economically destructive.
If the buyout is funded by life insurance, the surviving partner receives the death benefit income tax-free under IRC §101(a). This is one of the most powerful provisions in the tax code for business succession: a $5 million death benefit used to purchase a deceased partner's interest creates zero income tax liability for the buyer. The surviving partner's basis in the purchased interest equals the amount paid — in this case, $5 million. This becomes the new outside basis, which can be allocated to the underlying partnership assets (including Bitcoin) through a §754 election.
The estate reports the sale of the partnership interest as a capital transaction. Because the estate receives a stepped-up basis under IRC §1014 (basis equals fair market value at date of death), and the buy-sell price is (should be) approximately equal to FMV, the capital gain recognized on the sale is typically minimal or zero. The estate receives cash, pays little or no capital gains tax on the sale, and the estate tax is calculated on the total estate value including the partnership interest at FMV.
When a partnership makes payments to a deceased partner's estate for the partnership interest, IRC §736 governs the classification:
When a partner dies and their partnership interest receives a stepped-up basis under §1014, that step-up applies only to the outside basis. Without a §754 election, the partnership's inside basis in its Bitcoin remains unchanged — creating phantom gains when the BTC is eventually sold.
Example: A three-partner LLC holds 150 BTC with an average inside basis of $20,000 per coin. BTC trades at $100,000. Partner C dies. Under §1014, Partner C's estate gets a stepped-up outside basis. Without §754, when the partnership sells Bitcoin, the estate is allocated gain based on $20,000 basis — paying tax on appreciation that was already accounted for by the step-up. The §754 election fixes this through a §743(b) adjustment that aligns inside and outside basis for the transferee partner.
For Bitcoin partnerships with significant unrealized appreciation, the §754 election is not optional. Every Bitcoin partnership operating agreement should require a mandatory §754 election upon a partner's death.
The §743(b) adjustment applies only to the transferee partner (the estate or the buyer of the deceased's interest) — not to the entire partnership. The partnership must maintain separate basis schedules for the transferee, tracking which assets received basis adjustments and by how much. For a Bitcoin mining LLC with 150 BTC at different basis lots (each coin mined on a different date at a different price), the record-keeping is substantial. This is one of the strongest arguments for cross-purchase over entity redemption: in a cross-purchase, each buyer gets a clean basis equal to what they paid, without the complexity of §743(b) adjustments.
Bitcoin Mining Tax Strategy Resource
Mining is the most powerful tax strategy in Bitcoin — depreciation offsets, operational expense deductions, and bonus depreciation create tax efficiency that directly impacts buy-sell funding math. If your partnership involves mining, the tax structure matters more than you think.
Access the Mining Tax Strategy Guide →This is the most consequential structural decision in a bitcoin buy-sell agreement business partner arrangement, and the answer for Bitcoin-holding entities is almost always cross-purchase — for one reason that dominates all others: basis step-up.
In a cross-purchase, the surviving partners personally buy the deceased's interest. Their basis in the acquired interest equals what they paid. If Partner A pays $5 million for half of deceased Partner C's interest, Partner A's outside basis increases by $5 million. Through a §754 election, this additional outside basis flows through to the underlying partnership assets — including Bitcoin. The surviving partner's share of the Bitcoin treasury now has a higher inside basis, reducing capital gains on any future BTC disposition.
For a Bitcoin business where the primary asset has a low historical cost basis and massive unrealized appreciation, this basis step-up is worth potentially hundreds of thousands in future tax savings. It's the single most important structural advantage of cross-purchase.
In an entity redemption, the partnership buys back the deceased partner's interest. The surviving partners' ownership percentages increase proportionally, but their outside basis does not change. No additional basis flows through to the Bitcoin treasury. The surviving partners are left with the same low-basis BTC they had before — plus they may have triggered gains by selling BTC to fund the redemption.
The administrative simplicity is real: entity redemption requires fewer insurance policies (one per partner vs. one on each other partner), simpler accounting, and less coordination. For a five-partner business, entity redemption needs five policies; cross-purchase needs twenty. But for Bitcoin businesses, the tax cost of foregoing the basis step-up almost always exceeds the administrative savings.
The wait-and-see structure lets partners evaluate at the time of death. If BTC has appreciated dramatically and the basis step-up is worth millions, the surviving partners elect cross-purchase. If BTC has declined and the basis step-up is less valuable, the entity redeems — simplifying the transaction. This optionality is worth the additional drafting complexity, especially given Bitcoin's price volatility.
Bottom line: for Bitcoin-holding entities where the BTC treasury represents a significant portion of total value, cross-purchase is the default recommendation. Entity redemption should only be used when the number of partners makes cross-purchase impractical (five or more) or when the basis step-up is immaterial relative to the administrative burden.
For Bitcoin business partnerships, the following twelve provisions should be in every buy-sell agreement. If your current agreement is missing any of these, it was drafted for a different era.
Marcus Blackwell, Elena Torres, and David Park formed BTE Mining LLC in 2022 — a Wyoming LLC operating a Bitcoin mining facility in West Texas. By 2026, the operation had grown to 500 TH/s deployed hash rate, a 150 BTC treasury accumulated from mining rewards, and a below-market energy contract with a local wind farm operator at $0.035/kWh.
The partnership structure: equal one-third interests, Marcus as managing member responsible for operations and custody, Elena handling finance and energy procurement, David managing equipment purchasing and facility maintenance. The BTC treasury was held in a 2-of-3 multisig, with each partner holding one key.
On February 15, 2026, David Park died suddenly of a cardiac event at age 47. He was unmarried with two adult children (ages 22 and 24) who had no involvement in the business and no understanding of Bitcoin mining.
The partnership had a buy-sell agreement — a wait-and-see structure drafted by an attorney with digital asset experience. The agreement specified:
Each partner had designated a successor key holder in the operating agreement. David's successor was his attorney, James Chen, who had been trained on basic hardware wallet operations and held encrypted backup material in a secure vault.
Day 1 (February 15): Marcus and Elena learned of David's death. They immediately contacted James Chen, David's designated successor key holder. Per the operating agreement, they initiated the key rotation protocol — transferring all 150 BTC from the existing 2-of-3 multisig to a new 2-of-3 multisig with Marcus, Elena, and a temporary institutional custodian as key holders. The rotation was completed within 36 hours.
Week 1: Marcus and Elena notified their respective ILITs' trustees. David's estate was valued. BTC was trading at approximately $98,000 on the date of death. The 14-day VWAP came to $95,400. David's one-third interest in the BTC treasury: approximately $4.77 million (50 BTC × $95,400). Total estimated partnership value including equipment ($2.1 million), energy contract NPV ($1.8 million), and operational goodwill: approximately $18.6 million. David's one-third interest: approximately $6.2 million.
Week 2-3: The ILITs held $3 million each in death benefits. Under the wait-and-see agreement, the entity had the first option to redeem. Marcus and Elena evaluated: entity redemption would require selling approximately 22 BTC at current prices to bridge the gap between insurance proceeds and the total buyout price. They elected instead to have each partner's ILIT fund a cross-purchase — each buying half of David's one-third interest for approximately $3.1 million each. The insurance proceeds covered the purchase almost exactly.
Month 2: The §754 election was filed with the partnership's 2026 tax return. David's estate received a stepped-up basis in the partnership interest of $6.2 million. The §743(b) adjustment allocated approximately $4.5 million of basis step-up across the partnership's assets — primarily the BTC treasury and mining equipment — with respect to the interests acquired by Marcus and Elena's ILITs.
Month 3: David's estate received full payment. His two children split the proceeds evenly. They had no desire to be involved in Bitcoin mining, and the buy-sell agreement ensured they didn't have to be. Marcus and Elena continued operating BTE Mining with adjusted 50/50 ownership, updated insurance, and a new buy-sell agreement reflecting the two-partner structure.
The total cost of proper planning — buy-sell agreement drafting, ILIT creation, insurance premiums, operating agreement digital asset provisions — was approximately $85,000 over four years. The cost of not planning would have been measured in millions of lost value, months of operational downtime, and the probable dissolution of a profitable mining operation.
Beyond the buy-sell agreement for the business interest itself, Bitcoin partnerships should include a separate right of first offer for the entity's Bitcoin treasury. This provision requires the deceased partner's estate to offer the partnership's BTC holdings to the surviving partners before selling on the open market.
Why this matters: if the buy-sell agreement is structured as an entity redemption and the entity sells 50 BTC to fund the buyout, the remaining partners may want to purchase that BTC personally — at the entity's basis — rather than have the entity dump it on Coinbase. The first-offer right gives surviving partners the option to absorb the BTC at the entity level (maintaining the treasury) while funding the redemption through alternative means.
The first-offer right should specify:
The LLC operating agreement is where crypto business succession planning lives or dies. Standard operating agreements address capital accounts, profit allocation, and management authority. Bitcoin LLCs need additional provisions that most business attorneys don't think to include.
The operating agreement should specify exactly how custody of Bitcoin transfers upon a partner's death. If the entity uses multisig (e.g., 2-of-3 keys), the agreement must address:
For Bitcoin businesses that interact with exchanges, custody platforms, or DeFi protocols, the operating agreement should specify signing authority succession. Who can authorize exchange withdrawals if the partner who managed the entity's exchange accounts dies? Which partner has authority to interact with mining pool operators, hosting providers, and energy contract counterparties?
Document every platform, every account, every API key — and designate primary and secondary authorized signers for each. This information should be maintained in a secure digital vault that the surviving partners can access without the deceased partner's credentials.
Without a buy-sell agreement, the deceased partner's heirs inherit the partnership interest — including any claim to Bitcoin held in the entity. Heirs who have no interest in (or ability to run) the business become unwanted partners with voting rights on operational decisions. If the business uses multisig custody, the deceased partner's signing key becomes inaccessible, potentially freezing the Bitcoin treasury. A properly drafted buy-sell agreement prevents this by requiring surviving partners to purchase the deceased's interest at a predetermined price, funded by life insurance, so heirs receive cash and survivors retain control.
The optimal approach is a formula-based valuation using a 14-day volume-weighted average price (VWAP) from a specified composite of exchanges, applied as of the date of death. Fixed-price valuations become obsolete within months due to Bitcoin's volatility. The formula should also address embedded capital gains discounts, which exchanges to reference, and whether the IRC §2032 alternate valuation date election affects the purchase price. An independent appraisal serves as dispute resolution if either party challenges the formula by more than 10%.
Cross-purchase is generally preferred for Bitcoin-holding entities. Surviving partners receive a stepped-up cost basis in the portion purchased — including the underlying Bitcoin — reducing future capital gains tax on eventual BTC sales. Entity redemption is simpler (fewer insurance policies) but provides no basis step-up. A wait-and-see hybrid structure offers maximum flexibility by giving the entity first option to redeem, with surviving partners cross-purchasing any remainder based on market conditions at the time.
When a partner dies, their partnership interest receives a stepped-up basis to fair market value. However, this only adjusts the outside basis — not the partnership's inside basis in its Bitcoin. Without a §754 election, the estate pays tax on phantom gains when Bitcoin is sold. The election aligns inside and outside basis through a §743(b) adjustment, potentially saving millions in unnecessary taxes for Bitcoin partnerships with significant unrealized appreciation.
Each partner designates a successor keyholder in the LLC operating agreement. Within 48 hours of death, the surviving keyholders and successor initiate a key rotation: all Bitcoin transfers to a new multisig with updated keyholders. The deceased partner's key material is securely destroyed. This prevents security vulnerabilities from uncontrolled keys floating through probate.
Incapacitation is often worse than death because it doesn't trigger the death buy-sell provision. The buy-sell agreement should define disability as a separate trigger: inability to perform material duties for 90 consecutive days activates the disability buyout. Each partner also needs a durable power of attorney with explicit authority to manage cryptocurrency wallets, participate in multisig signing, and authorize Bitcoin transactions.
Yes — life insurance is the standard funding mechanism. In a cross-purchase arrangement, each partner (or their ILIT) owns a policy on the other partners' lives.
