[Coinbase Bitcoin Premium Index Negative for 20 Consecutive Days, Latest at -0.0467%] Odaily Planet Daily reports that the Coinbase Bitcoin Premium Index has remained in the negative premium range for 20 consecutive days, with the latest value at -0.0467%. This index measures the deviation of Coinbase (a mainstream compliant platform in the U.S.) BTC prices relative to the global average. A sustained negative value indicates heavier selling pressure in the U.S. market, a decline in risk appetite, capital outflows, or a rise in risk-averse sentiment. Historical data shows that prolonged negative premiums are often accompanied by the exit of U.S. institutional funds, warranting caution against short-term correction pressures.
