Bitcoin Collateral Loans: Everything You Need to Know

Understanding Bitcoin as Collateral

When you use Bitcoin as collateral, you're pledging your BTC to secure a loan without transferring ownership. The lender locks your Bitcoin in a secure contract (DLC, multisig, or custodial wallet depending on the platform), and if you default, they have the right to liquidate the collateral to recover their funds.

This differs fundamentally from traditional collateral like real estate or cars. Bitcoin's high volatility means collateral values can change dramatically in hours, requiring dynamic management and automated liquidation mechanisms to protect lenders.

Loan-to-Value Ratios and Collateral Requirements

The loan-to-value (LTV) ratio determines how much you can borrow against your Bitcoin. Most platforms offer 30-70% LTV, meaning:

• 30% LTV: Very safe, large collateral buffer, low liquidation risk
• 50% LTV: Balanced approach, standard for most borrowers
• 70% LTV: Maximum liquidity, higher liquidation risk, requires active monitoring

On Cadena Bitcoin, you can choose your LTV ratio based on your risk tolerance. Conservative borrowers opt for 30-40% LTV, while experienced traders comfortable with volatility may use 60-70% LTV.

Liquidation Mechanics and Protection

Liquidation occurs when your collateral value falls below the minimum threshold (typically 110-125% of the loan value). When this happens, the platform automatically sells your Bitcoin to repay the lender.

Cadena's DLC-based system provides transparent, on-chain liquidation triggered by oracle price feeds—no hidden liquidation engines or preferential treatment. You always know exactly when liquidation will occur based on publicly verifiable price data.

Best Practices for Collateral Management

• Start conservative: Your first loan should be 30-40% LTV to learn the mechanics safely
• Monitor regularly: Check your collateral ratio daily during volatile markets
• Add margin proactively: Don't wait until you're close to liquidation—add collateral when you reach 60% of the liquidation threshold
• Set price alerts: Use alerts to notify you when Bitcoin drops 10%, 15%, 20% from your loan price
• Understand grace periods: Some platforms offer time to add collateral; Cadena's DLCs settle automatically based on oracle data

Collateral Security: Custodial vs Non-Custodial

The biggest risk in Bitcoin collateral loans isn't liquidation—it's custody. Centralized platforms like BlockFi and Celsius held custody of borrowers' collateral and lost billions when they became insolvent.

Cadena's non-custodial approach using DLCs means your Bitcoin never enters a company wallet. It's locked in a contract controlled by cryptographic keys, not by corporate custodians who can misuse or lose your funds.
