Bitcoin-Backed Loan
What Is a Bitcoin-Backed Loan?
A Bitcoin-backed loan is a type of secured loan where Bitcoin serves as the collateral. Instead of selling Bitcoin to access liquidity, a borrower deposits it with a lender or protocol, receives cash or stablecoins in return, and reclaims the Bitcoin once the loan is repaid.
The appeal is straightforward: selling Bitcoin is a taxable event in many jurisdictions, though treatment varies, and it ends your exposure to any future price appreciation. A Bitcoin-backed loan lets you access liquidity while maintaining your position.
How Does a Bitcoin-Backed Loan Work?
The core mechanic is collateralization. A borrower deposits Bitcoin and receives a loan worth a percentage of that collateral’s value. This percentage is called the loan-to-value ratio (LTV). A typical LTV might be 50%, meaning $10,000 worth of Bitcoin unlocks a $5,000 loan. The gap between the two values acts as a buffer against price volatility.
If Bitcoin’s price drops and the collateral value falls toward the loan amount, the borrower faces a margin call: deposit more collateral or risk liquidation, where the lender sells enough Bitcoin to cover the outstanding debt.
Bitcoin-backed loans are available through two types of providers. Centralized platforms take custody of the deposited Bitcoin, manage the loan internally, and can offer a simpler user experience with fixed interest rates. Decentralized protocols (DeFi) handle the loan through smart contracts, removing the intermediary but requiring the borrower to manage their own collateral position directly.
The Custody Risk in Bitcoin-Backed Lending
A key risk many borrowers underestimate is custody. On a centralized platform, depositing Bitcoin as collateral means transferring it to a third party. That counterparty can be hacked, mismanage funds, or become insolvent. Once your Bitcoin leaves your self-custody, you are exposed to that platform’s operational and financial risk.
DeFi lending protocols reduce this by locking collateral in audited smart contracts rather than with a company, though smart contract bugs and oracle failures can introduce their own risks.
