How much Bitcoin collateral is required for a Better and Coinbase crypto-backed mortgage?

Borrowers must provide $250,000 in Bitcoin collateral to secure $100,000 in financing for a conventional home loan through the new partnership between Better and Coinbase. This 250% collateralization ratio allows homeowners to leverage their digital assets for a down payment without triggering capital gains taxes through a sale.

To secure a mortgage using Bitcoin through the new partnership between digital lender Better and exchange giant Coinbase, borrowers are required to pledge 250% of the loan amount in BTC collateral. Specifically, a borrower must deposit $250,000 worth of Bitcoin to receive $100,000 in credit toward a conventional home loan. This high collateral requirement is designed to buffer against Bitcoin’s notorious price volatility, ensuring the loan remains covered even during significant market downturns.

The process works by using Coinbase as the custodian for the digital assets, which are held in a cold storage environment while the mortgage remains active. By pledging the assets rather than selling them, U.S. borrowers can avoid the immediate tax implications of a crypto-to-fiat conversion, which would typically be taxed as a capital gain. This makes the product particularly attractive for 'HODLers' who believe in the long-term appreciation of Bitcoin but need liquidity for real estate purchases.

From a regulatory and market perspective, this move signals a growing intersection between traditional finance (TradFi) and decentralized assets. While crypto-backed lending has existed in the DeFi space for years, bringing it to the conventional mortgage market adds a layer of institutional legitimacy. However, the 250% ratio highlights the conservative approach traditional lenders are taking as they navigate the risks associated with digital asset price swings.

Investors and potential homebuyers should watch for how this collateral ratio evolves as Bitcoin matures. If the asset class shows reduced volatility over time, competition among lenders could drive down the 250% requirement, making these loans more accessible to the average investor. Furthermore, the success of this program may encourage other major US mortgage providers to integrate similar crypto-custody solutions to attract the growing demographic of crypto-wealthy individuals.
