The Coinbase Bitcoin Premium Index has remained in negative territory for 78 consecutive days, standing at ‑0.1145% in the latest reading and hitting the longest‑ever streak of negative premium. The indicator measures the Bitcoin price gap between Coinbase and other major exchanges and generally serves as a gauge for buying‑and‑selling demand within the United‑States market. Persistent negative readings signal comparatively low Bitcoin prices on Coinbase, which may point to weak investor appetite or heightened selling pressure from American traders.
