[BTC Maintains Fluctuation Between $80,000 and $87,000, Market Focuses on U.S. CPI and Fed Chair Kevin Warsh's Speech] The QCP Group report points out that BTC prices are fluctuating within the $80,000 to $87,000 range, with solid support at $80,000. Implied volatility in the options market remains high, and if BTC successfully breaks above $87,000, the target level points to $94,000. This Wednesday, U.S. CPI data will be released, followed by PPI data on Thursday. On Friday, Federal Reserve Chair Kevin Warsh will deliver a speech at the IMF-World Bank Annual Meetings. The market is closely watching how these data and policy signals will impact BTC's direction. AI Analysis: U.S. CPI data, as a core indicator of inflation, directly determines the marginal shift in Federal Reserve monetary policy. The release of this data will trigger a market repricing of the interest rate trajectory, thereby driving fluctuations in the risk premium of crypto assets. The actual CPI performance will directly validate inflation persistence and become a key variable influencing short-term market liquidity expectations. Investors need to adjust their positions based on inflation trends to respond to the volatile market movements caused by changes in macro policy expectations.
