Coinbase's Bitcoin premium index has turned positive at 0.0028%, reflecting a recovery in U.S. market buying sentiment. This marks the third positive trading day in the past week, following a 40-day period of negative premium. The index, which measures the price difference between Bitcoin on Coinbase and the global market average, is a key indicator of U.S. market dynamics. A positive premium suggests that Bitcoin's price on Coinbase is higher than the global average, indicating strong buying demand and active institutional inflows. This shift points to increased U.S. dollar liquidity and an optimistic investment outlook in the U.S. market.
