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 indicates that this surge was triggered by the Federal Reserve's 25 basis point interest rate cut and Powell's hawkish remarks, causing market panic that led Bitcoin to briefly drop below $100,000, while U.S. stocks fell approximately 3%. Historical data shows that a sharp rise in VIX often signals a local bottom for Bitcoin; for example, after VIX surged 116% in February 2018, Bitcoin rebounded from $6,891 to above $11,000; in August 2024, when VIX increased by 65%, Bitcoin bounced back from $54,000 to $64,000.
