Bitcoin Loans Explained: How to Borrow Against BTC Without Selling
A Bitcoin-backed loan lets you unlock liquidity from your BTC holdings — pay bills, invest elsewhere, or cover emergencies — without triggering a taxable sale. Here's exactly how it works, what it costs, and how to choose the right platform.
What it is: A Bitcoin-backed loan lets you pledge BTC as collateral and borrow cash or stablecoins against it — without selling your Bitcoin or triggering a capital gains event.
How it works: You deposit BTC, receive a loan at a percentage of its value (the LTV ratio), pay interest, and get your collateral back when you repay.
Key risk: If Bitcoin's price drops far enough, your LTV breaches the liquidation threshold and the platform automatically sells your collateral. A 50% BTC price drop can wipe out a 70% LTV position.
Tax note: Borrowing against BTC is not a taxable event in most jurisdictions. Liquidation events are — they're treated as disposals and trigger capital gains tax.
What a Bitcoin loan actually is
A Bitcoin loan — properly called a Bitcoin-backed loan or BTC-collateralized loan — is a secured loan where you pledge your Bitcoin as collateral and receive cash or stablecoins in return. You do not sell your BTC. You lock it with a lender, borrow against its value, pay interest, and get it back when you repay.
Think of it like a pawnshop for digital assets: hand over something valuable, receive cash, and once you repay, you get your asset back. The difference is that everything happens digitally — and in many cases, in minutes.
The appeal is straightforward. If you believe Bitcoin is going higher long-term, selling it today to meet a cash need means giving up future appreciation — and likely triggering a capital gains tax bill. A BTC-backed loan lets you have both: liquidity now and continued exposure to Bitcoin's price.
Platforms range from regulated companies like Ledn and Nexo to permissionless DeFi protocols like Aave. Each approach has different tradeoffs — covered throughout this guide.
Why borrow instead of selling?
The core argument is simple: if you expect BTC to be worth more in the future, selling it today is expensive in ways that don't show up in the loan interest rate.
Tax deferral (or avoidance)
In most jurisdictions, selling Bitcoin triggers a capital gains tax event. If you bought BTC at $20,000 and it's now at $80,000, selling $20,000 worth means you've realized a $60,000 gain per coin and owe tax on it immediately. Borrowing against that BTC instead is not a sale — no capital gains are realized until you actually dispose of the asset. For holders sitting on years of unrealized gains, the difference in tax liability can be enormous.
Maintaining long-term exposure
Long-term Bitcoin holders often believe the asset will appreciate significantly over a multi-year horizon. Selling to raise cash permanently reduces their position. A loan keeps the position intact — if BTC doubles in value while the loan is outstanding, you benefit from that appreciation in full once you repay.
The honest counterargument
Borrowing is not free. A 12% annual rate on a one-year loan is real money. And if BTC drops significantly during that period and you get liquidated, you lose your collateral. Borrowing against Bitcoin is a smart trade only if you genuinely plan to hold through volatility and the appreciation you expect outpaces your interest costs.
The break-even logic
If you borrow $40,000 at 12% APR for one year, you'll pay ~$4,800 in interest. If BTC appreciates more than 6% during that period (on a $80,000 collateral position), you've come out ahead compared to selling. If BTC drops significantly, the loan looks expensive in hindsight.
How Bitcoin loans work, step by step
Whether you use a centralized platform or a DeFi protocol, the flow is the same. Here's what happens from start to finish.
Choose a platform and your LTV
Decide what matters most — low rates, high LTV, no-KYC access, or the safety of a regulated platform. You'll also set your LTV ratio: how much to borrow relative to your collateral value. Lower LTV means less cash but a bigger buffer before liquidation.
Deposit your BTC as collateral
Transfer Bitcoin to the lender's custody address (CeFi) or a smart contract (DeFi). Your collateral is locked — you can't move or trade it while the loan is active. On DeFi, you'll use WBTC (Wrapped Bitcoin, an ERC-20 token backed 1:1 by BTC held by a custodian).
Receive the loan
Based on your collateral value and chosen LTV, the platform disburses your loan. CeFi platforms often offer USD bank transfers, USDC, or stablecoin options. DeFi protocols send stablecoins directly to your wallet. Speed varies: DeFi is near-instant; CeFi bank wires can take 1–3 business days.
Monitor your LTV
This is the part most beginners underestimate. As Bitcoin's price changes, your LTV changes. A 30% price drop on a 50% LTV loan brings your LTV to ~71% — manageable. The same drop on an 80% LTV loan pushes you past 114% — full liquidation. Set price alerts well above your liquidation level and have extra collateral or cash ready.
Repay and retrieve your Bitcoin
When you repay the principal plus accrued interest, your collateral is released. Most platforms allow early repayment with no penalty. On DeFi protocols, repayment and collateral release happen in the same transaction.
Worked example
You deposit 1 BTC worth $80,000. Platform offers 50% LTV → you receive $40,000 USDC. At 12% APR over 12 months, you owe $44,800 at repayment. If BTC is now worth $100,000, you paid $4,800 net interest to access $40,000 in liquidity while capturing $20,000 in BTC appreciation.
CeFi vs DeFi Bitcoin loans
Bitcoin holders have two fundamentally different routes to a BTC-backed loan: centralized platforms that hold your actual BTC, or DeFi protocols that use Wrapped Bitcoin (WBTC). Each has real advantages.
CeFi: simple, fiat-friendly, custodial
CeFi platforms like Ledn, Nexo, and Unchained take custody of your BTC, lend against it, and pay out in USD or stablecoins. You verify your identity once, then the experience feels like a regular financial product — dashboards, customer support, bank transfers. The main risk is the platform itself: if it's mismanaged or becomes insolvent (as Celsius and BlockFi were in 2022), your collateral is at risk.
DeFi: self-custody, no KYC, variable rates
DeFi protocols like Aave and MakerDAO run on smart contracts. You bridge BTC to WBTC, connect your Ethereum wallet, deposit into the protocol, and borrow against it — no identity documents, no intermediary. Your collateral sits in audited code, not a company's wallet. The risks shift from counterparty to technical: smart contract bugs, oracle manipulation, and WBTC custodian trust assumptions.
CeFi is better if you…
- Want fiat payouts to your bank account
- Prefer a guided, support-backed experience
- Don't want to manage a Web3 wallet
- Need fixed-rate certainty on costs
DeFi is better if you…
- Want to keep self-custody of your assets
- Prefer no KYC or identity verification
- Are comfortable with wallets and protocols
- Want transparent, on-chain collateral rules

Major Bitcoin loan platforms compared
Here's how the main BTC-accepting platforms differ on the metrics that matter most. All data from our provider research as of early 2026.
Ledn — CeFi
Rate: 12.4–13.9% · LTV: 50% · BTC only · KYC required · Proof of reserves (Armanino). Best for: Bitcoin-native borrowers who want a clean, regulated CeFi option with transparent attestations.
Nexo — CeFi
Rate: 2.9–13.9% · LTV: up to 80% · 60+ assets · KYC required · Instant credit line. Best for: borrowers who want the lowest possible CeFi rate and flexible open-ended terms. Lowest rates require NEXO token holdings.
Unchained Capital — CeFi
Rate: 14–16% · LTV: 40% · BTC only · KYC required · 2-of-3 multisig custody. Best for: security-maximalists. You hold one key — Unchained cannot move your BTC unilaterally. Higher rates are the trade-off.
YouHodler — CeFi
Rate: 3–26% · LTV: up to 97% · 50+ assets · KYC required · Swiss-regulated. Best for: high-LTV strategies. At 97% LTV you're extremely close to liquidation — use this only if you understand the risk.
Aave (WBTC) — DeFi
Rate: 2–15% variable · LTV: 82.5% · No KYC · Multi-chain · $15B+ TVL. Best for: DeFi-native users who want maximum LTV, lowest rates, and no counterparty risk. Requires WBTC and Web3 wallet.
MakerDAO (WBTC) — DeFi
Rate: 4–8% stability fee · LTV: 77% · No KYC · Mint DAI/USDS stablecoin. Best for: borrowers who want a specific stablecoin (DAI) and a well-established protocol with the longest track record in DeFi.

How to get your first Bitcoin loan
On a CeFi platform (Ledn, Nexo, etc.)
Create an account and complete KYC
Upload your ID and a selfie. Approval typically takes a few hours to one business day. Once verified, you'll have full access to the lending product.
Configure your loan
Select Bitcoin as collateral. Enter your desired loan amount or collateral amount — the platform calculates the other. Target 40–50% LTV to give yourself a comfortable buffer against a price drop.
Deposit BTC and receive funds
Send BTC to the platform's deposit address. The platform confirms receipt on-chain, then disburses funds — usually within minutes for stablecoin payouts, or 1–3 business days for USD bank transfers.
Set alerts and monitor
Know exactly at what BTC price your LTV hits 70%, 80%, and your liquidation threshold. Set price alerts in a separate app (CoinGecko, TradingView) well above the platform's margin call level.
On DeFi (Aave + WBTC)
Wrap your BTC to WBTC
Use a trusted bridge or a centralized exchange that supports WBTC withdrawals. WBTC is an ERC-20 token backed 1:1 by BTC held in custody by BitGo and other custodians.
Connect your wallet to Aave
Go to app.aave.com, connect MetaMask or Rabby. No sign-up, no email, no KYC — just your wallet.
Supply WBTC and borrow
Deposit WBTC as collateral and enable it as collateral in the dashboard. Then borrow your desired stablecoin (USDC, USDT, DAI). Keep your Health Factor above 1.5 — that's Aave's margin of safety metric.
Repay in one transaction
When you're ready, go to "Repay" in the dashboard, approve the transaction, and your collateral is released instantly in the same block.
Risks and how to manage them
Bitcoin loans are not risk-free. Here are the risks that actually matter, in order of importance.
1. Liquidation risk — the primary danger
Bitcoin is volatile. A 30% price drop on a 50% LTV loan brings your LTV to ~71% — uncomfortable but survivable. The same drop on an 80% LTV loan pushes you past most liquidation thresholds. Most platforms send margin call warnings, but in fast markets they arrive with little time to react.
How to manage it: Start at 40–50% LTV even if the platform allows 80%. Keep spare collateral pre-deposited or immediately accessible. Set your own price alerts at 60%, 70%, and 75% LTV — before any platform notification.
2. Platform / counterparty risk (CeFi)
Several major CeFi crypto lenders became insolvent in 2022 (Celsius, BlockFi, Voyager), and borrowers lost access to their collateral for months or years. This risk is real and not theoretical.
How to manage it: Choose platforms with proof-of-reserves attestations (Ledn and Nexo both publish these). Prefer platforms with regulatory standing. Consider Unchained's multisig model if the security tradeoff is worth the higher rates to you.
3. Smart contract risk (DeFi)
Audited protocols still carry code risk. Bugs, oracle manipulation, and governance attacks have led to losses across DeFi. Aave and MakerDAO have long track records with no critical exploits, but no protocol is zero-risk.
How to manage it: Stick to battle-tested protocols. Avoid newer or unaudited protocols regardless of how attractive the rates look.
4. WBTC trust assumptions
When you use DeFi with WBTC, you're trusting that the BTC backing WBTC (held primarily by BitGo) is sound. A WBTC custodian failure would affect collateral value. This risk is generally considered low but worth understanding before depositing significant amounts.
DeFi rate spikes
Variable DeFi borrow rates can spike dramatically when utilization is high. A stable 3% rate can temporarily jump to 20%+ during peak demand. If you need cost certainty, a CeFi fixed-rate loan is more predictable.
Tax treatment of Bitcoin loans
Tax treatment varies by jurisdiction. This is an overview — not advice. Consult a tax professional for your specific situation.
Taking the loan — generally not taxable
In the US, UK, and most of Europe, borrowing against Bitcoin is not a taxable event. You are not selling or exchanging your BTC — you're pledging it as collateral. The IRS does not treat borrowing as a disposition, so no capital gains are realized. This is the principal tax advantage of BTC-backed loans over selling.
Liquidation — this is taxable
If your collateral is liquidated, that is treated as a disposal. Per IRS guidance on virtual currency, capital gains are calculated on the difference between your BTC cost basis and its value at the time of liquidation — regardless of whether you received net proceeds. If you bought BTC at $20,000 and it was liquidated at $60,000, you owe capital gains tax on $40,000 per coin, even though you lost your collateral.
Interest deductibility
Interest paid on a BTC loan may be deductible as an investment expense in some jurisdictions if the loan proceeds were used for investment purposes. This varies significantly by jurisdiction and use of funds.
Keep records
Document everything: deposit dates and amounts, loan terms, interest payments, and any liquidation events. Good records make tax time straightforward; missing records make it expensive. Tools like Koinly and CoinTracker can help automate this for crypto positions.
Frequently asked questions
Can I borrow against Bitcoin without selling it?
Yes. A Bitcoin-backed loan lets you deposit BTC as collateral and receive cash or stablecoins in return. You keep ownership of your Bitcoin — when you repay the loan plus interest, your collateral is returned. In most jurisdictions, taking a loan is not a taxable event, unlike selling.
What is the typical interest rate on a Bitcoin loan?
Bitcoin loan rates in 2026 range from around 2.9% APR (Nexo at the best loyalty tier) to 16%+ for CeFi platforms like Unchained. DeFi protocols like Aave and MakerDAO offer rates in the 2–8% range, though they fluctuate with market demand. Most standard CeFi BTC loans land between 10–14% APR.
What LTV ratio can I get on a Bitcoin loan?
Standard Bitcoin loan LTV is 40–50% on most CeFi platforms (Ledn 50%, Unchained 40%). High-LTV platforms like YouHodler go up to 97%, but at sharply higher rates and liquidation risk. DeFi protocols using WBTC can offer 75–83% LTV (Aave up to 82.5%). Lower LTV means less cash but a much larger safety buffer against liquidation.
Is a Bitcoin loan a taxable event?
In most jurisdictions — including the US, UK, and most of Europe — taking a loan against your Bitcoin is not a taxable event. You are borrowing, not selling. However, if your collateral is liquidated, that is treated as a disposal and triggers capital gains tax. Always consult a tax professional for your specific situation.
What happens to my Bitcoin if the price crashes?
If Bitcoin's price falls and your LTV ratio exceeds the platform's liquidation threshold, the platform will partially or fully liquidate your collateral to repay the loan. Most platforms send margin call warnings first. To protect yourself: borrow at a conservative LTV (50% or lower), keep extra BTC ready to top up collateral, and set price alerts before your liquidation level.
Do I need to complete KYC to get a Bitcoin loan?
It depends on the platform. All major CeFi lenders (Ledn, Nexo, Unchained, YouHodler) require full ID verification. DeFi protocols like Aave and MakerDAO are permissionless — you only need a crypto wallet, no identity documents. CoinRabbit is a CeFi option that also skips KYC.
