The US Dollar Index (DXY) has surged past the 100 mark, reaching its highest level since August, raising concerns for Bitcoin and the broader cryptocurrency market. Analysts warn that the strengthening dollar may indicate a new cycle of liquidity tightening, as DXY forms a golden cross and nears critical resistance levels. Historically, Bitcoin has exhibited a negative correlation with the DXY, and recent movements underscore this inverse relationship. Traders are closely monitoring whether the DXY can break above 101, a move that could potentially lead to further bearish pressure on Bitcoin.
