Coinbase: No margin calls on bitcoin-backed mortgages

Coinbase said its crypto-backed mortgages will be priced about 0.5% to 1.5% above a standard 30-year mortgage, depending on the borrower's profile. The loans will not require margin calls or additional collateral. A decline in bitcoin's price will not alter loan terms or trigger liquidation. The collateral would only be at risk after 60 days of missed payments, consistent with traditional mortgage practices.
