币界网报道:Bitcoin surged 12% in mid-January as the U.S. Dollar Index (DXY) dropped 1.2%, signaling a potential inverse correlation between the cryptocurrency and the greenback. Analysts attribute Bitcoin's rally to weakening dollar strength and growing institutional interest, with spot Bitcoin ETF approvals fueling market optimism. The DXY decline reflects shifting Fed rate cut expectations, boosting risk assets. Meanwhile, Bitcoin's price rebound above $43,000 marks its strongest weekly performance since October 2023, though some traders caution about potential volatility ahead of the next FOMC meeting.
