The buy-borrow-die strategy is one of the most powerful wealth preservation techniques available to long-term Bitcoin holders. It's simple in concept: buy Bitcoin, borrow against it instead of selling, and pass it to your heirs — who inherit it at a stepped-up cost basis, wiping out decades of capital gains tax.
Billionaires have used this strategy with stocks, real estate, and fine art for generations. Bitcoin makes it both more powerful and more accessible.
The core idea: If your Bitcoin has appreciated significantly, selling it triggers capital gains taxes. But borrowing against it is not a taxable event. You get liquidity, keep your Bitcoin exposure, and your heirs inherit the BTC after you die — at today's fair market value, not your original purchase price.
How Buy-Borrow-Die Works with Bitcoin
Here's the strategy in three steps:
Step 1: Buy Bitcoin and Hold
You accumulate Bitcoin over time — through DCA, lump sum purchases, or mining. You hold it in cold storage or a qualified custodian. You never sell.
Your cost basis is what you paid. If you bought $50,000 of Bitcoin when the price was $10,000 and it's now worth $500,000, your unrealized gain is $450,000. Selling would trigger capital gains tax on that $450,000.
Step 2: Borrow Against Your Bitcoin
Instead of selling, you take out a loan using your Bitcoin as collateral. Bitcoin-backed loans are available from several lenders:
| Lender | LTV (Loan-to-Value) | Interest Rate | Custody | |--------|---------------------|---------------|---------| | Unchained Capital | Up to 40% | ~13–16% | Multi-sig, you keep a key | | Ledn | Up to 50% | ~10–14% | Custodial | | Coinbase | Up to 60% | Variable | Custodial | | Galaxy Digital | Up to 50% | Negotiated | Institutional | | Anchorage Digital | Up to 50% | Negotiated | Institutional |
Rates and terms change frequently. Verify current terms directly with lenders.
Example: Your Bitcoin is worth $500,000. You borrow $150,000 at 40% LTV. You receive $150,000 in cash — tax-free. Your Bitcoin remains in custody (or multi-sig), still appreciating. You pay interest on the loan, but interest rates are far lower than capital gains rates for large portfolios.

Step 3: Die (Pass It to Your Heirs)
When you die, your heirs inherit your Bitcoin portfolio. Under current US tax law (as of 2026), inherited assets receive a stepped-up cost basis — your heirs' cost basis is reset to the fair market value at the time of your death, not your original purchase price.
This eliminates the capital gains entirely.
If you bought Bitcoin at $10,000 and it's worth $2,000,000 when you die, your heirs inherit the Bitcoin with a cost basis of $2,000,000. If they sell immediately, they owe zero capital gains tax.
The outstanding loan balance (whatever you borrowed during your lifetime) is paid from the estate. The net result: your heirs get the appreciated Bitcoin with no capital gains, minus the loan balance.
Why Bitcoin Is Ideal for Buy-Borrow-Die
The strategy works with any appreciating asset, but Bitcoin has several properties that make it especially powerful:
Asymmetric appreciation potential. Bitcoin's long-term price trajectory — as modeled by the Power Law, Saylor Model, and Stock-to-Flow frameworks — suggests continued appreciation over decades. The longer you hold without selling, the larger the unrealized gain, and the bigger the stepped-up basis benefit at death.
No cash flows to tax. Unlike rental real estate (which generates taxable rental income) or dividend-paying stocks, Bitcoin held in cold storage produces no taxable events whatsoever until you sell. You can hold for 20 years and owe nothing.
Portability and divisibility. Unlike real estate, Bitcoin can be divided, transferred, or used as collateral without legal complications, title searches, or closing costs.
Borderless collateral. Bitcoin-backed loans are available globally. As the asset class matures, more lenders are entering the space with better rates and terms.
The Numbers: A 20-Year Example
Let's model a realistic scenario using the Bitcoin retirement calculator:
Starting position (2026):
- 1 Bitcoin purchased in 2018 for $6,500
- Current value: ~$85,000
- Unrealized gain: ~$78,500
Projected value (2046, base case):
- Using Power Law model: ~$2,000,000+
- Unrealized gain: ~$1,993,500
- Capital gains tax if sold (20% long-term): ~$398,700
Buy-Borrow-Die outcome:
- Borrow $400,000–$600,000 over 20 years at 40–50% LTV
- Pay ~$50,000–$100,000 in interest (tax deductible if investment loan)
- Heirs inherit 1 BTC at $2,000,000 stepped-up basis
- Heirs pay: $0 in capital gains
- Net savings vs. selling: ~$300,000–$400,000 in taxes avoided
This is why wealthy holders never sell their Bitcoin.
Risks and How to Manage Them
Buy-borrow-die isn't risk-free. The primary danger is liquidation — if Bitcoin's price drops sharply, your lender may issue a margin call and liquidate your Bitcoin to cover the loan.
Managing Liquidation Risk
Keep LTV ratios conservative. Most lenders allow up to 50–60% LTV, but sophisticated borrowers rarely exceed 25–30%. This gives you a substantial price buffer before a margin call.
- At 25% LTV: Bitcoin would need to drop 70–75% before liquidation risk
- At 50% LTV: Bitcoin would need to drop 40–50% before liquidation risk
- At 60% LTV: Bitcoin would need to drop only 30–35% before liquidation risk
Bitcoin's largest drawdowns historically: -83% (2018), -77% (2022), -93% (2011). A 25% LTV survives a 75% drawdown.
Use multi-sig custody where possible. Unchained Capital's collaborative custody model (2-of-3 multi-sig) means neither you nor the lender can move the Bitcoin alone. This eliminates the counterparty risk of a custodial lender going bankrupt (see: Celsius, BlockFi).
Keep cash reserves. Hold enough liquid assets to pay down the loan if Bitcoin falls sharply. A rule of thumb: have 6–12 months of interest payments plus enough to reduce LTV if prices drop 50%.
Borrow in tranches, not all at once. Don't take your maximum borrowing capacity all at once. Take what you need, maintain low LTV, and add to the loan as Bitcoin appreciates.
Tax Law Risk
The stepped-up basis benefit is a feature of current US tax law and could change. Several proposals over the years have attempted to eliminate or cap stepped-up basis for large estates. As of 2026, it remains intact, but this is a genuine legislative risk for very long-horizon planning.
Mitigation: Work with an estate planning attorney to structure your Bitcoin holdings in ways that are resilient to multiple tax scenarios (trusts, LLCs, gifting strategies). This strategy should be part of a broader estate plan, not a standalone bet on tax law remaining unchanged.
Tax Treatment of the Loan and Interest
Borrowing is not income. Loan proceeds are not taxable. This is the foundation of the strategy.
Interest may be deductible. If you use the loan proceeds for investment purposes (buying more assets, funding a business), the interest may be deductible as investment interest expense. Consult a tax advisor on your specific situation.
Loan repayment is not taxable. Paying back the principal doesn't create a taxable event.
What IS taxable: If you use the Bitcoin as collateral and the lender liquidates it (sells it to cover the loan), that is a taxable sale event. Avoiding liquidation isn't just about preserving your position — it also avoids an unwanted tax bill.
Setting Up the Strategy: Step by Step
1. Accumulate Bitcoin into a single, secure position. The strategy works best with a meaningful Bitcoin position — ideally at least $100,000–$250,000 in value. Consolidate across wallets and exchanges.
2. Move to cold storage or qualified custodian. For the collateral position, you have two options:
- Multi-sig with a lender (Unchained Capital): you retain one key, the lender holds one, a third key is your backup. Best for security.
- Custodial with a lender (Coinbase, Ledn): simpler, but the lender holds your Bitcoin. Choose regulated, insured custodians only.
3. Calculate your target borrowing capacity. At 25–30% LTV, determine how much you can borrow safely:
- $500,000 BTC × 25% = $125,000 available
- $1,000,000 BTC × 25% = $250,000 available
4. Draft an estate plan with a Bitcoin-literate attorney. The stepped-up basis benefit only applies if your Bitcoin actually passes to your heirs. An attorney can help with:
- Naming beneficiaries correctly
- Setting up a Bitcoin trust to avoid probate
- Documenting your Bitcoin holdings and access procedures
5. Plan the loan payments. Factor interest costs into your cash flow planning. At 12% annual interest, a $200,000 loan costs $24,000/year. This is manageable if you're deploying the capital productively.
6. Document everything for your heirs. Your heirs need to know:
- Where your Bitcoin is held (custodian or self-custody)
- How to access it (seed phrases, multi-sig keys)
- What loans are outstanding
- Who your estate planning attorney is

Buy-Borrow-Die vs. Selling: Comparison
| Approach | $1M BTC position | Tax at sale | Heirs receive | |----------|-----------------|-------------|---------------| | Sell now | Realize $950K gain (bought at $50K) | ~$190K (20% LTCG) | $810K in cash | | Borrow and hold | Keep BTC exposure | $0 now, low interest cost | BTC at stepped-up basis, minus loan balance | | Borrow, die, heirs inherit | BTC grows to $5M | $0 ever | ~$4.8M (minus loan) at zero cost basis |
The difference between "sell now" and "buy-borrow-die" compounds dramatically over time. Every year you hold and borrow instead of selling, the unrealized appreciation grows — and the stepped-up basis benefit at death grows with it.
Who This Strategy Makes Sense For
Best for:
- Long-term Bitcoin holders with significant unrealized gains ($100K+)
- People who need liquidity without wanting to exit their Bitcoin position
- Estate planning — anyone who wants to pass Bitcoin to children or grandchildren
- High-income earners in the 20% capital gains bracket (where tax savings are largest)
Less suitable for:
- People who may need to access all their capital quickly (illiquid collateral)
- Highly leveraged borrowers who can't weather a Bitcoin correction
- Those with no estate planning documents in place
- Small positions where the legal and custodial costs outweigh the tax savings
The Bigger Picture: Bitcoin as Generational Wealth
The buy-borrow-die strategy is ultimately about a fundamental shift in how you think about Bitcoin. It's not a trade — it's an asset you accumulate, hold, and pass down.
Families that held Amazon stock through its entire run, borrowing against it instead of selling, created generational wealth. Bitcoin, with its fixed supply, global network, and growing institutional adoption, has the properties of a generational asset.

Frequently Asked Questions
Is the buy-borrow-die strategy legal? Yes. Borrowing against assets is not a taxable event under US tax law. The stepped-up basis for inherited assets is a long-standing feature of the tax code (Section 1014). This is the same strategy used by ultra-wealthy families for generations with stocks, real estate, and art. It's aggressive tax planning, not evasion.
What happens to my loan when I die? Outstanding loan balances are paid from your estate before heirs receive their inheritance. Your heirs receive the Bitcoin (at stepped-up basis) minus whatever is owed to the lender. If the Bitcoin has appreciated significantly, the loan balance is a small fraction of the total value.
What if the stepped-up basis law changes? This is the primary legislative risk. Congress has proposed limiting stepped-up basis in several budget proposals. If the law changes, the strategy's tax benefit is reduced or eliminated. Work with an estate attorney to have backup structures (trusts, gifting strategies) in place.
Can I do this with a small amount of Bitcoin? The strategy makes economic sense when the capital gains tax saved exceeds the cost of the loan (interest) plus any legal/setup fees. For most people, this threshold is around $100,000–$250,000 in Bitcoin value with significant unrealized gains.
Is borrowing against Bitcoin safe? It's safe if managed conservatively — low LTV ratios (25–30%), strong custodians, and cash reserves to handle volatility. It's dangerous if you borrow at high LTV, use a poorly capitalized lender, or have no plan for a Bitcoin price drop.
Do I owe taxes when I take out a Bitcoin-backed loan? No. Borrowing is not income. You only owe taxes if your collateral is liquidated (sold) by the lender, or if you otherwise dispose of the Bitcoin.
How is this different from using Bitcoin on DeFi protocols? On-chain lending protocols (like Aave or Compound) work similarly mechanically, but with different risk profiles — smart contract risk, liquidation via algorithm, no regulatory protection. Centralized lenders offer regulated custody, human-managed liquidation processes, and legal protections. For a strategy designed to preserve generational wealth, most advisors recommend centralized, regulated lenders.
