Borrow Against Bitcoin: Rehypothecation Risk, Custody, and Collateral Control Explained by Cryptalend

Borrowing against Bitcoin allows investors to access liquidity without selling their assets. For experienced holders, the decision is rarely about access to capital alone. It is about how risk is structured behind the scenes.

One of the most overlooked risks in crypto lending is rehypothecation.

What Is Rehypothecation?

Rehypothecation occurs when a lending platform reuses your collateral. Instead of holding your Bitcoin securely, the platform may:

• Lend it to other borrowers
• Deploy it into yield strategies
• Use it as collateral in external systems

This introduces counterparty risk that is separate from market volatility.

Why This Matters for Borrowers

Most borrowers focus on:

• Loan-to-Value (LTV)
• Liquidation thresholds

But even with conservative LTV, collateral can still be exposed if it is reused.

This means your risk is no longer limited to market movement. It now depends on how the platform operates internally.

Real-World Context

In past crypto lending failures, platforms that reused collateral across multiple strategies faced cascading liquidity issues when market conditions tightened. This affected withdrawals and overall platform stability.

Custody and Collateral Segregation

A more structured approach separates custody from lending operations.

In this model, collateral is held with BitGo:

• Assets are fully segregated
• Collateral is not pooled or reused
• Custody operates independently from lending activity

This reduces exposure to external leverage and counterparty chains.

Ownership Structure

Another key distinction is ownership.

Under this structure:

• The borrower retains legal ownership of the collateral
• The platform does not take ownership
• The platform only has liquidation rights if predefined LTV thresholds are breached

This creates a clear boundary between control and risk enforcement.

Hypothetical Example

A BTC holder deposits $2M and borrows at 30% LTV.

In this scenario:

• The collateral remains segregated in custody
• It is not deployed externally
• Ownership remains with the borrower

The only condition under which action is taken is if LTV approaches liquidation levels.

Why This Model Matters

A no-rehypothecation structure combined with segregated custody shifts risk back to what borrowers can actually manage:

• Market movement
• LTV decisions
• Timing of intervention

Rather than hidden exposure to external counterparties.

Final Thought

When borrowing against Bitcoin, understanding liquidation is essential.

But understanding how your collateral is handled is what defines real risk.
