The Coinbase Bitcoin Premium Index has remained in negative territory for 10 consecutive days, currently at -0.0648%, according to Coinglass data. This index measures the price difference between Bitcoin on Coinbase and the global average, with a negative value indicating weaker demand in the U.S. and potential capital outflows. The sustained negative premium suggests a lower risk appetite among U.S. investors, contributing to the ongoing pressure on Bitcoin prices. Additionally, the fear and greed index continues to reflect bearish sentiment in the market, further impacting Bitcoin's performance.
