Deep Tide TechFlow News, December 19, according to CoinDesk, the Chicago Board Options Exchange Volatility Index (VIX) surged 74% on December 18, marking the largest single-day increase since February 2018 and the second highest in history. Analysts point out that this surge was triggered by the Federal Reserve's 25 basis point rate cut and Powell's hawkish remarks, causing Bitcoin to briefly drop below $100,000, with the U.S. stock market falling about 3%.

Historical data shows that a significant spike in VIX often indicates that Bitcoin has hit a local bottom. For instance, after the VIX surged 116% in February 2018, Bitcoin rebounded from $6,891 to over $11,000; when the VIX rose 65% in August 2024, Bitcoin rebounded from $54,000 to $64,000.
