Bitcoin is finally getting paid. Major platforms are turning idle BTC into productive collateral, letting holders tap liquidity without selling, and potentially earn on top. With Coinbase unveiling a BTC‑backed lending service that lets you borrow up to 86% of your stack in USDC, the door just opened to smarter capital efficiency—if you manage the risks like a pro.

What’s happening

Coinbase announced a Bitcoin‑backed lending product at the Bitcoin 2025 Conference. Users can deposit BTC and borrow up to 86% of its value in USDC, with loans reportedly secured by Moro decentralized smart contracts recognized for security and immutability. The pitch: preserve BTC exposure, unlock liquidity, and gain access to interest‑bearing opportunities around ~5% while distancing from the failures of past custodial yield schemes.

Why this matters to traders

This is a shift from passively holding BTC to actively optimizing it: - Capital efficiency: Keep your BTC upside while using borrowed USDC to trade, hedge, or earn yield. - Liquidity on demand: Access cash without selling and potentially triggering taxable events. - Product breadth: As more lenders compete, expect tighter spreads, varied LTV tiers, and integrations with institutional‑grade venues.

Key mechanics: LTV, rates, and liquidations

- LTV: Up to 86% means thin margin for error. Volatility can rapidly push loans toward liquidation. Conservative traders operate at 25–50% LTV for safety. - Rates: Borrow APR and potential USDC yields are variable. Always compare net spread after fees. - Liquidations: If BTC drops and LTV breaches thresholds, collateral can be partially or fully liquidated. Know the trigger levels, fees, and grace periods.

Actionable strategies to consider

• Conservative carry: Borrow USDC at a modest LTV (e.g., 30–40%), deploy into conservative, transparent yield venues. Keep a reserve to top up collateral in drawdowns.
• Cash‑flow without selling: Use borrow‑against‑BTC to fund fiat needs short‑term, preserving exposure. Remember, interest accrues—model duration and exit.
• Market‑neutral basis: Deploy USDC to buy BTC spot and short perpetuals/futures to capture funding/basis. Profits hinge on funding staying positive; monitor basis and funding flips.
• Tax optimization: Borrowing instead of selling may defer taxes in some jurisdictions. This is not tax advice—consult a professional.

Risk checklist (don’t skip)

• Price risk: BTC drawdowns can trigger liquidation. Stress test for 25–40% downside moves.
• Rate risk: Borrow APR can rise while yield sources compress, killing your spread.
• Counterparty/custody: Understand where BTC is held, rehypothecation policies, and insurance coverage.
• Smart contract: Even “audited” contracts carry non‑zero risk. Verify audits and upgrade/pausing powers.
• Stablecoin risk: USDC carries issuer and depeg risks, however remote; monitor market conditions.
• Operational: Downtime during volatility, oracle delays, and slippage can impair top‑ups or exits.
• Regulatory: Oversight is increasing; terms can change quickly. Read the fine print.

What to watch next

- Spread dynamics: Track borrow APR vs. net yield on USDC venues or basis funding—act only when the spread is compelling after risk and fees. - LTV buffers: Maintain ample collateral buffer and auto‑alerts for price moves that push LTV toward danger zones. - Transparency: Demand clear disclosures on collateral management, liquidation rules, oracle sources, and smart‑contract controls.

Bottom line

BTC‑backed lending can transform a dormant BTC stack into a flexible funding source and measured yield engine. The edge goes to traders who size conservatively, protect against liquidation, and treat yield as compensation for risk—not a guarantee. Use the tools, respect the risks, and let capital efficiency work for you, not against you.
