Bitcoin’s Coinbase Bitcoin Premium Index has remained below zero for 50 consecutive days, the longest negative streak on record, with Coinglass showing the latest reading at -0.0696%. The index compares Bitcoin prices on Coinbase with the global market average, and a negative reading typically signals heavier U.S. selling pressure, weaker risk appetite, rising risk aversion or capital outflows. The prolonged stretch underscores continued softness in U.S.-linked demand for Bitcoin.
