CoinEx News: CoinGlass data showed on July 12 that the Coinbase Bitcoin Premium Index had remained below zero for 55 consecutive days since May 19, the longest negative streak in its history. A negative reading means BTC trades more cheaply on Coinbase than in offshore markets, showing that US-dollar buyers have not been chasing the price as aggressively. Until the Coinbase premium returns above zero, a price rebound lacks confirmation from the main US-dollar venue, leaving BTC more dependent on offshore buying.
