Selling Bitcoin to pay for something is almost always the wrong move. You trigger a taxable event, you permanently exit your position, and you miss future appreciation. Bitcoin-backed loans solve this — you put your Bitcoin up as collateral, receive cash, and keep your Bitcoin position intact.
This guide covers everything: how Bitcoin loans work, what loan-to-value ratios are safe, how to avoid margin calls, which lenders to use, and how the borrow-don't-sell strategy compounds over a lifetime.
How Bitcoin-Backed Loans Work
A Bitcoin-backed loan is a collateralized loan where your Bitcoin secures the debt. The mechanics:
- You deposit Bitcoin with the lender as collateral
- The lender sends you cash (USD, USDC, or a wire transfer) — typically 30–60% of your Bitcoin's value
- You pay interest on the loan — rates range from 5% to 14% annually depending on the lender and your LTV
- You repay the loan (or roll it) to get your Bitcoin back
- If Bitcoin price drops and your LTV exceeds a threshold, you either post more collateral or get partially liquidated
The loan is not a taxable event. You receive cash without realizing any capital gains. This is the cornerstone of the buy-borrow-die strategy: accumulate Bitcoin, borrow against it for living expenses, and pass it to heirs with stepped-up cost basis (eliminating lifetime gains permanently).
Loan-to-Value (LTV) Ratios Explained
LTV = Loan Balance ÷ Collateral Value × 100
If you deposit 1 BTC worth $100,000 and borrow $50,000, your LTV is 50%.
Every lender has three LTV thresholds:
| LTV Level | What It Means | |-----------|---------------| | Initial LTV (30–60%) | Maximum you can borrow at origination | | Margin Call LTV (65–75%) | Lender notifies you to add collateral or repay | | Liquidation LTV (80–85%) | Lender sells your Bitcoin to repay the loan |
Example: Margin call scenario
- Deposit 1 BTC at $100,000 → borrow $50,000 (50% LTV)
- Bitcoin drops to $72,000 → LTV rises to 69% → margin call issued
- You have 24–72 hours to either post additional BTC or repay part of the loan
- If Bitcoin drops to $62,500 → LTV hits 80% → automatic liquidation begins
This is why LTV discipline is the most important variable in Bitcoin-backed lending.
Safe LTV Framework
The right initial LTV depends on your risk tolerance and how much Bitcoin price volatility you can absorb before a margin call:
| Starting LTV | Bitcoin Drop Before Margin Call (at 70% threshold) | |--------------|-----------------------------------------------------| | 30% | -57% drop required | | 40% | -43% drop required | | 50% | -29% drop required | | 60% | -14% drop required |
Recommendation for most borrowers: 30–40% initial LTV.
Bitcoin has had multiple 50%+ drawdowns (2018: -84%, 2022: -77%). At 30% LTV, even an 80% Bitcoin crash doesn't trigger liquidation — it only pushes you to the margin call threshold. At 50% LTV, a 30% Bitcoin drop — which happens routinely in every cycle — triggers a margin call.
The 30% rule: Never borrow more than 30% of your Bitcoin's current value if you want to sleep well during bear markets. This leaves a 57% buffer before a margin call at most lenders.
Major Bitcoin Lending Platforms (2026)
Unchained Capital
Best for: Long-term HODLers, larger loans, self-custody advocates
Unchained offers multi-signature loans where you retain keys in a 2-of-3 multisig arrangement — Unchained holds one key, you hold two. This is the most secure structure in Bitcoin lending: even if Unchained goes bankrupt, your Bitcoin is protected.
- LTV: Up to 40% initial
- Rates: 13–14% APR
- Minimum loan: $10,000
- Custody: Multi-signature (you hold 2 of 3 keys)
- Margin call LTV: 67%
Unchained also offers Bitcoin IRAs and collaborative custody products — worth considering for multi-service users.
Ledn
Best for: Lower interest rates, flexible loan sizes
Ledn offers Bitcoin-backed loans with competitive rates and a clean product for straightforward collateralized lending.
- LTV: Up to 50% initial
- Rates: 9.5–11% APR (varies with market conditions)
- Minimum loan: $1,000
- Custody: Ledn holds Bitcoin (full custodial)
- Margin call LTV: 75%
Ledn publishes proof-of-reserves attestations quarterly — an important transparency signal given the history of custodial lending failures.
Milo Credit
Best for: Using Bitcoin as collateral for real estate purchases
Milo offers crypto mortgages — you can buy a home or investment property using Bitcoin as collateral rather than cash. This is the direct application of Bitcoin lending for large purchases.
- LTV (crypto collateral): Varies by property type
- Rates: Competitive with conventional mortgages
- Use case: Primary residence, investment property, refinancing
BlockFi / Celsius / FTX — What Happened (and Why It Matters)
Three major Bitcoin lending platforms that collapsed between 2022–2023:
- Celsius — Froze withdrawals in June 2022, filed for bankruptcy; customers lost billions
- BlockFi — Collapsed after FTX contagion in November 2022
- FTX — Exchange and lending product collapsed simultaneously
The pattern: All three used customer Bitcoin for yield generation (rehypothecation) — lending your collateral to third parties to earn yield. This created hidden counterparty risk: your "custodied" Bitcoin wasn't actually held 1:1.
What to look for when choosing a lender:
- Proof of reserves — does the lender publish regular attestations?
- No rehypothecation — is your collateral used for yield generation?
- Multi-signature custody — do you retain any keys?
- Regulated entity — is the lender licensed in your jurisdiction?
The safest Bitcoin loans are fully collateralized with transparent custody and no rehypothecation. Unchained's multisig model is the gold standard.
The Borrow-Don't-Sell Strategy in Practice
Here's how a long-term Bitcoin holder might use borrowing over multiple decades:
Phase 1: Accumulation (years 1–10) DCA into Bitcoin. No borrowing. Build the stack.
Phase 2: First borrow (major expense arises) You have 2 BTC worth $300,000 and need $75,000 for a down payment or other large expense. Borrow at 25% LTV ($75,000). Pay interest at 12% = $9,000/year. Bitcoin appreciates 40% over the next 4 years to $420,000. Your LTV drops from 25% to ~18%. You can either repay the loan from income or roll it forward.
Phase 3: Refinancing and rolling As Bitcoin price rises, your LTV naturally decreases. You can:
- Repay the original loan (using income, not Bitcoin)
- Roll into a new loan at the same dollar amount but lower LTV
- Draw an additional loan against the new higher collateral value
Phase 4: Retirement phase (living off loans) With a large Bitcoin position and no income, you take annual loans against your Bitcoin (5–7% of total position) rather than selling. Tax-free cash flow. The loans accrue until death, when your heirs inherit Bitcoin with stepped-up cost basis — eliminating all accumulated capital gains. The estate sells a small fraction of Bitcoin to repay loans, keeping the rest.

Interest Rate Math: Is Borrowing Worth It?
You're paying interest to keep your Bitcoin. Is it worth it?
The break-even analysis:
If you borrow at 12% APR and your Bitcoin appreciates 30% annually (historical average), you're net +18% per year by borrowing instead of selling.
If Bitcoin appreciates 0% (flat year), you're paying 12% for nothing but you haven't realized capital gains and haven't exited your position.
If Bitcoin depreciates 20% and you're paying 12% interest, you're net -32% — worse than selling. But you can also wait for recovery without the interest, while a seller has permanently exited the position.
The real calculation:
| Scenario | Borrow at 12% | Sell Position | |----------|--------------|---------------| | BTC +50% year | Net +38% (kept gains) | 0% (exited) | | BTC +20% year | Net +8% (kept gains) | 0% (exited) | | BTC flat year | Net -12% (interest cost) | 0% (exited) | | BTC -30% year | -42% (BTC loss + interest) | -30% (exited at loss) |
Over multiple years, if your long-term conviction on Bitcoin is correct, borrowing dominates selling in almost every scenario — except severe prolonged bear markets where you also face margin call risk.
Bottom line: Borrow at 30% LTV or less. Keep emergency reserves. Don't use loan proceeds for risky investments. Think in 4+ year timeframes.
Managing Margin Call Risk
The three tools for avoiding liquidation:
1. Low LTV Buffer
The cheapest protection. Start at 30% LTV. At current prices, you'd need a 57% Bitcoin crash to reach a 70% LTV margin call. That's a serious bear market, but with 4 months of warning as price declines.
2. Cash Buffer
Maintain a cash reserve equal to at least 2× your annual interest payment. This lets you repay a portion of the loan during a crash, reducing LTV without selling Bitcoin.
Example: $100,000 Bitcoin loan at 12% APR = $12,000/year interest. Keep $25,000 in cash ready to deploy. If Bitcoin drops 30% (LTV goes from 30% to 43%), you can repay $20,000 of principal, dropping LTV back to 31%.
3. Monitor LTV Weekly
Lenders send margin call notices, but by the time you receive one, you have 24–72 hours to respond. Monitor your LTV dashboard weekly. If BTC price drops 15%, assess whether to post more collateral proactively.
Responding to a Margin Call
When you receive a margin call:
- Add more Bitcoin collateral (posts within hours, lowers LTV immediately)
- Repay part of the loan principal (reduces numerator, lowers LTV)
- Accept partial liquidation (lender sells enough BTC to bring LTV down — you keep the rest)
Option 3 is the worst outcome — forced selling at the worst possible time (during a crash). Options 1 and 2 should always be the response if you have resources.
Tax Treatment of Bitcoin Loans
Bitcoin loans are not taxable income. Loan proceeds are debt, not income.
- Origination: Not taxable
- Interest payments: Potentially deductible if loan is used for investment purposes (consult a CPA — investment interest deduction has limitations)
- Repayment: Not taxable
- Collateral returned: Not taxable (you never "sold" it)
- Margin call liquidation: Taxable! If your lender liquidates Bitcoin to repay the loan, that's a deemed sale. The proceeds are applied to your loan, but the gain/loss is reported on your tax return.
This is another reason to manage LTV carefully — forced liquidation creates an unexpected tax bill during a bear market.

Bitcoin Loans vs. HELOC vs. Margin Loans
How do Bitcoin-backed loans compare to other collateralized borrowing options?
| Feature | Bitcoin Loan | HELOC | Margin Loan (Stocks) | |---------|-------------|-------|---------------------| | Collateral | Bitcoin | Home equity | Securities | | Typical rates | 9–14% APR | 7–9% APR | 6–12% APR | | Max LTV | 50–60% | 80–90% | 50% (Reg T) | | Margin call risk | Yes (volatile asset) | No | Yes | | Tax deductibility | Limited | Yes (mortgage interest) | Investment interest rules | | Approval process | Hours (no income check) | Weeks (income/credit) | Days (brokerage account) | | Asset appreciation | Bitcoin exposure maintained | Home equity continues | Portfolio exposure maintained |
Bitcoin loans have higher rates than HELOCs but require no income verification, close in hours, and keep your Bitcoin position working. For HODLers who can't qualify for traditional credit or don't want to liquidate, they're an excellent tool.
Frequently Asked Questions
What happens to my Bitcoin loan if the lender goes bankrupt? This depends entirely on the loan structure. With Unchained's multisig model, your Bitcoin is in a 2-of-3 multisig wallet — you hold 2 keys, so you can recover funds even if Unchained fails. With custodial lenders (Ledn, others), you become an unsecured creditor in bankruptcy and may not recover full collateral. This is exactly what happened to Celsius customers. Prefer multi-signature or self-custody structures for larger amounts.
Can I take a Bitcoin loan inside my IRA? Generally no — prohibited transaction rules prevent IRA holders from using IRA assets as collateral for personal loans. Bitcoin-focused IRAs (iTrustCapital, Bitcoin IRA) hold Bitcoin for retirement, but the assets cannot be used as collateral. Self-directed IRA rules are complex here — consult a specialist before attempting any collateralized lending with retirement assets.
How do taxes work if I use a Bitcoin loan to invest in other things? If you use loan proceeds for investment purposes (buying stocks, real estate, or more Bitcoin), the interest may qualify as investment interest expense, deductible up to the amount of net investment income on Schedule A. Keep records of how you use loan proceeds. Consumer use (personal purchases, vacation) doesn't qualify.
What's the minimum amount to make a Bitcoin loan worthwhile? The fixed costs — origination fees, legal documentation at some lenders — typically make loans under $10,000 economically inefficient. Most lenders have minimum loan amounts of $1,000–$10,000. For loans under $10,000, consider simply DCA-selling a small position rather than paying the overhead of a formal loan.
Can I use a Bitcoin loan to buy more Bitcoin? Yes, and this creates leveraged Bitcoin exposure — your upside is amplified but so is your downside and margin call risk. This is an aggressive strategy used by sophisticated traders. The math only works if Bitcoin appreciates faster than your interest rate. At 12% APR, you need Bitcoin to return more than 12% annually to break even — net of volatility risk and margin call exposure. Only appropriate for a portion of a large position with substantial cash reserves.
What credit score is required for a Bitcoin loan? Most Bitcoin lenders don't check credit scores — they're overcollateralized lenders who rely entirely on your Bitcoin collateral, not your creditworthiness. This is one of the key advantages for people with poor credit, no US credit history (recent immigrants), or who simply want to avoid hard credit inquiries. Some lenders may do a soft pull or income verification for very large loans ($1M+).
