Golden Finance reported that, 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. Analysis points out that this surge is due to the Federal Reserve's 25 basis point interest rate cut and Powell's hawkish remarks causing market panic, leading Bitcoin to temporarily drop below $100,000, and U.S. stocks to fall about 3%. Historical data shows that a sharp rise in VIX often signals that Bitcoin is reaching a local bottom; for example, 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 bounced back from $54,000 to $64,000.
