The Coinbase Bitcoin Premium Index has recorded a negative premium for 60 consecutive days, marking the longest negative streak since its inception. According to Coinglass data, the index's latest value stands at -0.0908%. This surpasses the previous record of 40 consecutive days of negative premium earlier this year and the 30-day streak during the "1011 crash" period. Historical trends suggest that extended negative premiums often coincide with the withdrawal of US institutional funds, indicating potential short-term pullback pressure in the market.
