Bitcoin has traded at a discount on Coinbase versus Binance for 50 straight days, with the Coinbase Bitcoin Premium Index still negative as of July 7-8, the longest streak on record. The latest reading of -0.0742% shows BTC slightly cheaper on the U.S. exchange, a sign of weaker American demand that has coincided with roughly eight weeks of spot Bitcoin ETF outflows and no sustained inflow run yet for BlackRock’s IBIT.
