Shenchao TechFlow news, July 7, according to the latest data from Coinglass, the Coinbase Bitcoin premium index has been in negative premium territory for 50 consecutive days (from May 19 to now), with the latest value at -0.0742%. Previously, the index was in negative premium for 40 consecutive days from January 16 to February 24 this year, setting the longest "consecutive negative" record since the index was launched, surpassing the about 30 consecutive days of negative premium during the "1011 crash". Historical data shows that long-term negative premium is often accompanied by the withdrawal of US institutional funds, and one should be cautious about short-term correction pressure.
