San FranciscoCoinbase now offers fixed-rate loans against bitcoin holdings.
It pushes the largest US crypto exchange further into consumer banking territory.
Bitcoin trades at $87,140, up 14.4% in a week, and Coinbase says it already holds $1.4 billion in loans against $3 billion of collateral.
Fixed rates remove interest-rate surprises, but a bitcoin price drop still triggers automatic liquidation.
Coinbase has not disclosed how much borrowing demand it expects for the fixed-rate product.
