[Bitcoin Holds $82,500 Support Level, Market Volatility May Increase] Wintermute analysis indicates that influenced by the U.S. Consumer Price Index and adjustments in the artificial intelligence sector, the Nasdaq Index fell 5.52% over the week, while Bitcoin dropped 1.99%, briefly breaking below but then reclaiming and holding the $82,500 support level. Altcoins overall declined by 5.69%, with capital flowing back from high-beta and micro-cap tokens to Bitcoin and Ethereum. Currently, Bitcoin has been consolidating around $82,500 for over three weeks. A breakout above $87,000 would confirm an upward trend, while a breach of the support level could lead to a potential dip to $70,000. With the Federal Open Market Committee's interest rate decision, midterm elections, and the release of Q3 U.S. stock earnings reports, overall market volatility may increase.
