Woofun AI data shows that the Coinbase Bitcoin Premium Index has maintained a negative premium for 60 consecutive days, extending from May 19 to the present with a current reading of -0.0908%. This duration exceeds the previous record of 40 consecutive days observed between January 16 and February 24, as well as the approximately 30-day negative period during the "1011 crash". Historical patterns indicate that extended negative premiums often coincide with US institutional capital outflows, warranting caution regarding short-term downward pressure.
