According to CoinGlass, the Coinbase Bitcoin Premium Index has remained in a negative premium range for 75 consecutive days from May 19 to the present. The latest figure is -0.0973%. Previously, the index recorded a negative premium for 40 consecutive days from January 16 to February 24 this year, setting the longest continuous negative record since the index's inception. This surpassed the previous record of approximately 30 consecutive negative days during the crash on October 11 last year. Historical data shows that a prolonged negative premium often coincides with the outflow of funds from US institutional investors from the market.
