Internet reports that recently, U.S. President Trump has publicly criticized Federal Reserve Chairman Powell on many occasions and hinted that he might be fired, which has aroused widespread market attention. Analysts pointed out that if Trump fired Powell, it could seriously weaken the independence of the Federal Reserve, cause the market to lose confidence in U.S. monetary policy, and even trigger an economic recession. In this context, cryptocurrencies may gain more attention due to their decentralized nature, especially Bitcoin, which may be seen as a tool to hedge risks in the traditional financial system. Historically, bitcoin prices have been closely following the Nasdaq index (despite the multiplier effect), and the U.S. stock market has remained sluggish recently, but bitcoin has bucked the trend, leading to market speculation that bitcoin is "decoupling" from the Nasdaq index. Although it is impossible to say whether it will really happen, if Trump really fires Powell, the market may finally determine the decoupling effect.
