The divergence between the cryptocurrency market's fear and greed index, like the BTC Fear & Greed Index, and actual price trends can be complex. A high fear index might coexist with price increases if, for example, long - term investors view dips as buying opportunities, contrary to short - term sentiment. Conversely, extreme greed could precede a price slump as over - enthusiasm leads to overvaluation. Such divergence often signals a shift in market sentiment or emerging market inefficiencies, urging investors to combine index analysis with other metrics for a comprehensive market understanding.
