The Federal Reserve press conference on March 20 is highly anticipated. The current environment is characterized by high uncertainty, with tariff fluctuations and inflation expectations being the focal points. The direction of Trump's policies tests the independence of the Federal Reserve, and Powell's statements are particularly crucial. If hawkish signals are released, BTC may fall below the 80,000 mark; if dovish signals are given, BTC could challenge the strong resistance at 85,000.
