According to Matrixport analysis, US President Trump has threatened to replace Federal Reserve Chairman Powell, although it is unclear whether he has the power to do so. This event is considered a key factor in the recent weakening of the US dollar. In history, Bitcoin has shown a significant negative correlation with the US dollar, and the current weakening of the US dollar may prompt American investors to refocus on Bitcoin, highlighting its potential as a hedge against the depreciation of the US dollar.
