Borrowing against crypto lets you access liquidity without selling your holdings, maintaining your long position while getting cash or stablecoins for other uses. In 2026, this is a mainstream practice: Coinbase offers Bitcoin-backed loans to US users, Aave and Compound handle billions in on-chain collateralized loans, and specialized services like Unchained Capital provide Bitcoin-secured financing for large borrowers. The mechanics, risks, and when it makes sense depend heavily on which platform you use and how much leverage you take. Here’s the practical guide.
How does borrowing against crypto collateral work?
Crypto collateral loans are overcollateralized — a core feature that makes borrowing against crypto safer for lenders without requiring credit checks. This protects the lender if prices drop without requiring credit checks on the borrower. The basic mechanics:
- Deposit collateral (BTC, ETH, or other accepted assets)
- Borrow against it, typically 50-80% of collateral value (loan-to-value ratio)
- Pay interest on the borrowed amount
- If collateral value drops below a threshold (liquidation threshold), your collateral is partially or fully liquidated to repay the loan
Example: Deposit 1 BTC (worth $100,000). Borrow $50,000 USDC at 50% LTV. You have $50,000 liquid and still maintain BTC exposure. If BTC drops to $65,000 (triggering your liquidation threshold), $50,000 of your BTC is sold to repay the loan.
Which platforms offer crypto-backed loans in 2026?
- Coinbase Borrowing: BTC-backed loans for US users through Coinbase. Simple interface, uses Coinbase custody. Rates and LTV ratios determined by Coinbase’s underwriting. Best for: US users wanting simplicity and Coinbase custody security.
- Aave (DeFi): Borrow USDC, DAI, or other stablecoins against ETH, WBTC, and 20+ collateral types. Self-custodial, collateral stays in the smart contract, not with any company. Interest rates variable based on market utilization (typically 3-8% for stablecoins). Liquidation threshold: varies by asset (ETH: 82.5% LTV max on Aave v3). Best for: users comfortable with DeFi and wanting non-custodial loans.
- Morpho: Built on Aave and Compound, optimizes rates by matching lenders and borrowers directly when possible. Better rates than base Aave in many conditions. Best for: active DeFi users wanting optimized rates.
- Unchained Capital: Bitcoin-secured loans for larger borrowers ($10K minimum). 2-of-3 multisig custody, Unchained holds one key, you hold two. Annual interest rates: 10-14%. Best for: large Bitcoin holders wanting institutional-grade Bitcoin loans without DeFi complexity.
- Ledn: Bitcoin-backed loans internationally. B2X product lets you “double” BTC exposure by borrowing USD against BTC, buying more BTC. Best for: international users wanting BTC-native loan products.
How does liquidation work and how do you avoid it?
Liquidation is the primary risk in crypto loans. It occurs when your collateral value falls below the liquidation threshold:
- On Aave: if your health factor drops below 1.0 (meaning your collateral value is no longer sufficient vs. borrowed amount), liquidators can repay up to 50% of your debt and receive collateral at a discount
- Liquidation events cascade, if BTC drops 20% quickly, many positions hit liquidation simultaneously, creating sell pressure that can amplify the decline
Liquidation avoidance strategies:
- Maintain conservative LTV, borrow 30-40% instead of the maximum allowed. At 40% LTV on BTC, the price needs to drop 60% to trigger liquidation.
- Set up monitoring alerts (DeFi Saver, Instadapp) that notify you before your health factor approaches liquidation threshold
- Keep stablecoin reserves to add collateral or repay loan if price drops
- Use longer-duration centralized loans (Unchained, Coinbase) when available, these typically have fixed rates and more explicit liquidation processes than automated DeFi systems
Frequently Asked Questions
Is borrowing against crypto taxable?
Taking out a loan (borrowing) is not a taxable event in the US, you’re receiving cash in exchange for collateral, not selling the asset. Interest payments on crypto-backed loans may be deductible as investment interest (consult a tax professional). However, if your collateral is liquidated to repay the loan, the liquidation is a taxable sale, you realize a capital gain or loss based on the difference between your cost basis and the liquidation price. This unexpected taxable event is one of the most commonly missed tax obligations in DeFi.
What LTV should you use for a crypto-backed loan?
Conservative approach: 30-40% LTV provides significant buffer against liquidation. At 40% LTV, BTC needs to drop 57% from your entry to trigger liquidation (collateral value = loan amount). At 70% LTV, a 30% price drop triggers liquidation, Bitcoin regularly moves 30%+ in short periods. For DeFi loans, DeFi Saver’s Safe Loan functionality maintains your LTV automatically by selling collateral or using flash loans to adjust position. The less tolerance you have for monitoring, the lower LTV you should use.
When does borrowing against crypto make financial sense?
Best use cases: accessing liquidity without triggering a taxable sale of appreciated crypto (especially relevant for large long-term holdings where capital gains would be substantial), funding real-world expenses while maintaining long-term crypto exposure, and leveraged BTC accumulation (borrow stablecoins, buy more BTC, amplifies both gains and losses). Poor use cases: funding high-risk trades, meeting ongoing living expenses (you need predictable cash flows, not volatile collateral), or borrowing at high LTV in volatile market conditions where liquidation risk is elevated.
