According to online reports, Federal Reserve Chairman Powell said that he would not make an immediate policy response to Trump's new round of trade tariffs, nor would he rush to cut interest rates due to market fluctuations and recession expectations. Recently, the crypto market has been dragged down by concerns about a global trade war and a correction in U.S. stocks. Powell's speech further weakened the market's expectations for easing policies and was not conducive to bulls pushing up prices in the short term. Bitunix analysts 'view: BTC's short-term pressure range is US$84,500-US$83,800, with short-term support of US$80,000. If BTC prices fail to stabilize the US$80,000 mark, they will enter a deeper adjustment area. Traders are advised to control their positions, strictly implement stop losses, and wait for the situation to become clearer.
