The Chicago Options Exchange's (CBOE) Volatility Index (VIX), a measure of Wall Street's fear, experienced a significant increase of 74% on the 18th, indicating potential volatility in the market. Historically, when the VIX surges, Bitcoin (BTC) and the S&P 500 index tend to bottom out. In previous instances, such as February 2018 and August 2022, VIX spikes have correlated with subsequent rebounds in BTC. Analysts suggest that the recent VIX surge may imply a possible bottom for BTC and a potential recovery. However, it's important to note that market conditions can change rapidly, and investors should exercise caution and conduct their own research before making any investment decisions.
