Coinbase's Bitcoin Premium Index has turned positive for two consecutive days, reaching 0.0231%, according to Coinglass data. This marks a shift in U.S. market sentiment, as five of the past ten trading days have shown a positive premium, following a previous 40-day streak of negative premiums. The positive premium indicates that Bitcoin's price on Coinbase is higher than the global market average, suggesting strong buying demand and increased institutional interest in the U.S. market. This development reflects a recovery in investor sentiment and ample U.S. dollar liquidity, signaling a potential shift towards a more optimistic market outlook.
