In the cryptocurrency market, affected by the lower opening of US stocks, Bitcoin quickly fell to around $81,000 last night, rebounding only after the US stock market closed, and was reported at $82,571 at the time of writing, down nearly 1% in 24 hours.

The market is focused on the Federal Reserve's monetary policy decision tonight. Although it is expected that interest rates will remain unchanged, which has become a market consensus, investors still hope to find clues from the "dot plot" and Powell's comments at the press conference about policymakers' assessment of the potential impact of the trade war, and when the Fed will cut interest rates again.
