Borrowing against your Bitcoin is one of the most useful financial tools available to long-term holders. You get liquidity without selling, without triggering capital gains tax, and without giving up your Bitcoin exposure during what could be its most valuable years.
This guide covers everything: how Bitcoin-backed loans work, which lenders are worth using, how to calculate your liquidation price, and the mistakes that get people wrecked.
What Is a Bitcoin-Backed Loan?
A Bitcoin-backed loan (also called a crypto-collateralized loan) works like a home equity line of credit — except instead of your house, you're pledging your Bitcoin.
Here's the basic mechanic:
- You deposit Bitcoin as collateral with a lender
- The lender extends you a loan in USD (or stablecoins) — typically 25–60% of your Bitcoin's value
- You pay interest on the loan
- You repay the loan, and the lender returns your Bitcoin
- If Bitcoin's price drops far enough that your collateral no longer covers the loan, the lender liquidates some or all of your Bitcoin
The key point: borrowing is not a taxable event. You receive cash without selling Bitcoin, so you owe no capital gains tax on the borrowed amount.
How Loan-to-Value (LTV) Works
LTV is the ratio of your loan to the value of your collateral. It's the most important number in Bitcoin lending.
Example:
- You have 1 BTC worth $85,000
- You borrow $25,500
- Your LTV = $25,500 / $85,000 = 30%
Most lenders set a maximum LTV (what they'll lend) and a liquidation LTV (when they'll sell your Bitcoin to cover the loan).
| LTV Threshold | What It Means | |---------------|---------------| | Initial LTV (40–60%) | Maximum you can borrow at origination | | Margin call LTV (70–75%) | Lender warns you to add collateral or repay | | Liquidation LTV (80–85%) | Lender liquidates your collateral automatically |
Calculating Your Liquidation Price
This is the number every borrower needs to know before taking out a loan.
Formula: Liquidation Price = Loan Amount ÷ Liquidation LTV
Example:
- You borrow $30,000 against 1 BTC at 30% initial LTV (BTC = $100,000)
- Lender liquidates at 80% LTV
- Liquidation price = $30,000 ÷ 0.80 = $37,500
Bitcoin would need to fall from $100,000 to $37,500 — a 62.5% drop — before you're liquidated. That's a substantial buffer, but Bitcoin has had drawdowns of 77–93% historically.
At 50% initial LTV:
- Borrow $50,000 against 1 BTC ($100,000)
- Liquidation price = $50,000 ÷ 0.80 = $62,500
- Bitcoin drops only 37.5% before liquidation
Conservative borrowing (25–35% LTV) is what separates Bitcoin holders who successfully use this strategy from those who get wiped out.
Top Bitcoin-Backed Loan Providers
Unchained Capital
Best for: Long-term holders who want maximum security and multi-sig custody
Unchained uses a 2-of-3 multi-signature setup: you hold one key, Unchained holds one key, and a third key is yours as backup. Neither party can move the Bitcoin alone. This eliminates the risk of Unchained going bankrupt and taking your Bitcoin with them (as happened with Celsius and BlockFi customers).
- LTV: Up to 40–50%
- Rates: ~13–16% APR
- Minimum: $10,000 loan / ~$25,000 BTC collateral
- Custody: Multi-sig (you keep a key)
- Best for: Serious long-term holders, large amounts

Ledn
Best for: US and international borrowers wanting competitive rates
Ledn is a regulated Bitcoin lending platform with a straightforward product and solid track record. They offer transparent proof-of-reserves attestations.
- LTV: Up to 50%
- Rates: ~10–14% APR
- Minimum: ~$1,000 loan
- Custody: Custodial (Ledn holds your BTC)
- Best for: Mid-size borrowers, international users
Coinbase
Best for: Existing Coinbase users, convenience
Coinbase offers Bitcoin-backed loans to US customers through their platform. Rates are variable and generally higher than dedicated lenders, but the UX is simple.
- LTV: Up to 60%
- Rates: Variable, typically higher than dedicated lenders
- Minimum: Varies
- Custody: Custodial (Coinbase holds your BTC)
- Best for: Small loans, existing Coinbase users
Institutional Lenders
For holders with $500,000+ in Bitcoin, institutional lenders like Galaxy Digital, Anchorage Digital, and Silvergate (where available) offer negotiated rates and terms. Rates are often lower, LTV ratios are more flexible, and borrowing capacity is larger. These require direct outreach.
What to Look for in a Bitcoin Lender
Before you deposit Bitcoin with any lender, check:
Custody model:
- Do they use multi-sig? Can you verify your Bitcoin is held on-chain?
- Do they publish proof-of-reserves?
- What happens to your Bitcoin if the lender goes bankrupt?
Liquidation process:
- Is liquidation automated (instant, no warning) or manual (with notice)?
- Do they send margin call warnings before liquidating?
- What's the exact liquidation LTV?
Rate structure:
- Is the rate fixed or variable?
- Are there origination fees?
- Prepayment penalties?
Regulatory status:
- Is the lender registered/regulated in your jurisdiction?
- What legal protections do you have?
Step-by-Step: Getting a Bitcoin-Backed Loan
Step 1: Calculate how much you want to borrow
Start with a conservative LTV — 25–35% is the safe zone. This gives you a large buffer against Bitcoin volatility.
If Bitcoin is at $85,000 and you want to borrow at 30% LTV:
- Maximum loan = $85,000 × 30% = $25,500
- Liquidation at 80% LTV = $25,500 ÷ 0.80 = $31,875 (BTC would need to drop ~62%)
Step 2: Choose a lender
For amounts over $50,000: Unchained Capital (multi-sig security). For amounts under $50,000: Ledn (lower minimum, competitive rates).
Step 3: Complete KYC/AML
All regulated lenders require identity verification. Have your government ID ready. The process typically takes 1–3 business days.
Step 4: Set up custody
For Unchained: You'll generate a multi-sig vault with their software. Your Bitcoin is transferred to a 2-of-3 multi-sig address, not a company-controlled wallet.
For custodial lenders: You transfer Bitcoin to a wallet address they provide. This is less secure than multi-sig — only use regulated lenders with proof-of-reserves.
Step 5: Transfer your Bitcoin collateral
Once the custody arrangement is set up, you send Bitcoin to the collateral address. The lender will confirm receipt and fund your loan.
Step 6: Receive your funds
Most lenders fund via ACH or wire transfer within 1–3 business days after collateral is confirmed.
Step 7: Monitor your LTV
Set up price alerts. If Bitcoin drops significantly, you'll want to either:
- Add more Bitcoin as collateral (reduces LTV)
- Repay part of the loan principal (reduces LTV)
Don't wait for a margin call — act proactively.
Interest Rates and True Cost
Bitcoin-backed loans are expensive relative to mortgage rates but cheap relative to the alternative of selling Bitcoin and losing future appreciation.
Calculating the real cost:
If Bitcoin appreciates 40% per year (conservative based on historical 4-year cycles) and you borrow at 14% APR:
- Opportunity cost of selling: 40% gain on the full amount
- Cost of borrowing: 14% interest
- Net advantage of borrowing vs. selling: ~26% per year in preserved upside
This math changes dramatically in a bear market. If Bitcoin falls 30% and you're paying 14% APR, you're losing on both fronts.
Interest is tax-deductible in some cases. If you use loan proceeds for investment purposes (buying more assets, funding a business), the interest may qualify as investment interest expense — deductible up to your net investment income. Consult a tax advisor.
Managing Risk: How to Avoid Liquidation
Getting liquidated is worse than it sounds. Not only do you lose your Bitcoin at the worst possible price, but the sale is a taxable event (you owe capital gains on the amount sold).
Risk management principles:
Borrow conservatively. 25–35% LTV, not 50–60%. The extra liquidity isn't worth the liquidation risk.
Keep a cash reserve. Hold enough liquid assets to either add collateral or repay a portion of the loan if Bitcoin drops 30–50%.
Dollar-cost average your borrowing. Don't take out the maximum loan all at once. Borrow in tranches as you need it.
Set price alerts. Know your margin call price and liquidation price before you borrow. Set alerts at 10%, 20%, and 30% drops.
Use a lender with manual liquidation. Some lenders (like Unchained) give you time to respond to margin calls before liquidating. Automated liquidation (common on DeFi protocols) happens instantly with no warning.
Don't re-leverage. Taking out a Bitcoin loan to buy more Bitcoin (leveraging up) multiplies both your upside and your liquidation risk. It's a strategy for experts, not long-term HODLers.
Bitcoin Loans vs. DeFi Lending
On-chain DeFi protocols like Aave, Compound, and MakerDAO also offer Bitcoin-collateralized borrowing (using wrapped Bitcoin). The mechanics are similar, but the risk profile is different.
| Factor | Centralized Lender | DeFi Protocol | |--------|-------------------|---------------| | Custody | Lender (or multi-sig) | Smart contract | | Liquidation | Often manual with notice | Automated, instant | | Counterparty risk | Lender solvency | Smart contract bugs | | KYC required | Yes | No (permissionless) | | Privacy | Low | High | | Rate | Fixed or variable | Variable (market-driven) | | Minimum | Often $10K+ | Often $0 |
For generational wealth strategies and large positions, centralized regulated lenders are generally the safer choice. Smart contract risk (bugs, exploits) is real — hundreds of millions in DeFi has been stolen through contract vulnerabilities.
Tax Treatment of Bitcoin Loans
Borrowing: not taxable. Loan proceeds are not income.
Repaying: not taxable. Paying back principal doesn't create a taxable event.
Interest: potentially deductible. If proceeds are used for investment purposes.
Liquidation: taxable. If the lender sells your Bitcoin to cover the loan, that's a disposition — you owe capital gains tax on any appreciation. This is a key reason to avoid liquidation at all costs.
Holding the underlying BTC: not taxable. Bitcoin in cold storage or with a lender as collateral doesn't create a taxable event.
This tax treatment is why borrowing against Bitcoin is so powerful — you access liquidity in a completely tax-neutral way, preserving all your future appreciation and the stepped-up basis benefit for your heirs.

How Much Can You Borrow?
A practical guide based on position size:
| BTC Value | Conservative (30% LTV) | Moderate (40% LTV) | Note | |-----------|----------------------|--------------------|------| | $50,000 | $15,000 | $20,000 | Ledn minimum territory | | $100,000 | $30,000 | $40,000 | Good for most needs | | $250,000 | $75,000 | $100,000 | Unchained ideal range | | $500,000 | $150,000 | $200,000 | Institutional rate possible | | $1,000,000 | $300,000 | $400,000 | Negotiate institutional terms |

Common Mistakes
Borrowing at maximum LTV. The lender's max is not your safe limit. Lenders make money when you get liquidated — that's not your goal.
Not knowing your liquidation price. Know it before you sign anything. Liquidation price = loan amount ÷ liquidation LTV.
Using the loan proceeds for consumption. Borrowing against an appreciating asset to buy a car or vacation means you're paying high interest rates for depreciating spending. Use loans for investment-grade purposes.
Ignoring the lender's financial health. Celsius and BlockFi users lost billions when those companies failed. Research your lender's business model, proof-of-reserves, and regulatory status.
Treating Bitcoin loans like a credit card. Revolving debt management with Bitcoin collateral is complex. Keep loans simple: borrow once for a specific purpose, repay on a schedule.
Frequently Asked Questions
Is it safe to borrow against Bitcoin? It can be, at conservative LTV ratios with a regulated, solvent lender. The main risks are: lender insolvency (use multi-sig or regulated custodians), Bitcoin price volatility triggering liquidation (use low LTV), and smart contract risk (avoid DeFi for large amounts).
Do I lose my Bitcoin when I take a loan? No — you pledge it as collateral, but you don't sell it. You get it back when you repay the loan. The exception is if you get liquidated: the lender sells your Bitcoin to cover the outstanding loan balance.
What credit score do I need? Bitcoin-backed loans are collateral-based, not credit-based. Most lenders don't check your credit score. KYC/AML identity verification is required, but your credit history is typically irrelevant.
How long can I keep the loan open? Loan terms vary by lender. Some offer 12-month terms with renewal options; others offer open-ended credit lines. Ask about renewal terms before committing.
Can I borrow against Bitcoin in an IRA? This is complicated. Bitcoin in an IRA (via a Bitcoin IRA provider) is generally not available as collateral for personal loans. The IRA's tax-advantaged status restricts what you can do with the assets. See our Bitcoin IRA guide for details.
What's the minimum amount of Bitcoin I need to borrow against? Dedicated lenders like Unchained typically require $25,000–$50,000 in Bitcoin collateral minimum. Coinbase has lower minimums for existing customers. For small amounts, some DeFi protocols have no minimums but come with different risks.
What happens if the lender goes bankrupt? With a multi-sig lender like Unchained, bankruptcy doesn't give them access to your Bitcoin — you still hold a key. With custodial lenders, you become an unsecured creditor if the company goes bankrupt. This is what happened to Celsius and BlockFi customers, who lost access to their funds for years. Choose your lender structure carefully.
