Bitcoin is moving into the mortgage business, with a structure designed to sidestep both tax bills and margin calls.
Coinbase and mortgage lender Better have launched a home loan product that uses Bitcoin as collateral. The key innovation, detailed on Presidio Bitcoin Jam, is the absence of a volatility-induced margin call. As long as the borrower makes their monthly payment, the Bitcoin collateral stays untouched, regardless of market price. This solves the primary friction that has plagued crypto-backed lending.
Steve, Presidio Bitcoin Jam:
- The eye-popping thing about this is it's a Bitcoin-backed loan.
- But if the price of Bitcoin goes down, you don't have to pony up more Bitcoin.
The product targets a conservative 40% loan-to-value ratio, requiring $500,000 in Bitcoin to secure a $200,000 loan. This large cushion is a bet on Bitcoin's long-term price floor, allowing the lender to absorb volatility. The ultimate ambition is more systemic: to get these loans purchased by government-sponsored enterprises like Fannie Mae, bridging volatile digital assets with federal housing infrastructure.
DK, Presidio Bitcoin Jam:
- The real breakthrough is these loans can be purchased by Fannie Mae.
- That is big because that's government-backed.
This development mirrors a separate corporate trend of using Bitcoin on balance sheets without selling. On Bitcoin And, David Bennett analyzed GameStop's recent filing, which showed the company held its 4,709 Bitcoin throughout the 2025 slump. Instead of selling, GameStop used the coins as collateral in a covered call strategy with Coinbase Credit to generate yield, debunking narratives of forced liquidation.
Together, these moves signal Bitcoin's maturation from a speculative asset into a functional tool for credit and corporate treasury management. The mortgage product specifically serves the Bitcoin-rich but cash-poor, offering an alternative to triggering capital gains taxes through a sale. The real test will be whether legacy institutions like Fannie Mae accept the bridge being built.
