Coinfomania and CoinTurk News EN both report a 90-day negative Coinbase Bitcoin Premium Index but credit different individuals as the source of the observation.
What all sources agree on
Coinbase Bitcoin Premium Index has recorded a 90-day negative streak.
The negative streak stretches from May 19 to August 16.
The index reading is close to -0.1% (Coinfomania states -0.1066%; CoinTurk News EN states ‘close to -0.1%’).
This is described as the longest such negative streak on record.
A negative index reflects Bitcoin trading at a discount on Coinbase relative to Binance, suggesting weaker U.S. buying demand.

Treat the 90-day negative streak, its date range, and the roughly -0.1% reading as established since both outlets agree on these figures; the identity of who first reported or is credited with the observation is unresolved, as the two accounts cannot both be correct.
