Recently, the market phenomenon is quite interesting——when the US stock market soars, the crypto circle just lays flat and sideways; when the US stocks are stagnant, the crypto market starts to decline; and when the US stock market crashes significantly, the crypto market plunges even more. It seems that the crypto market has long become a follower of the US stock market. Or to put it bluntly, whatever happens in the US stock market, the crypto market is led around by the nose. This correlation is becoming increasingly obvious, especially in recent times, with BTC's movements more directly reflecting this trend.
