The Crypto Fear & Greed Index is a valuable sentiment tool for market analysis:

1. **Reference Value**:  
   - Extreme fear often signals potential buying opportunities.  
   - Extreme greed may indicate overbought conditions and impending corrections.  

2. **How to Use**:  
   - Combine with technical indicators (e.g., RSI, MACD) for confirmation.  
   - Use it to identify contrarian entry/exit points.  
   - Monitor shifts in sentiment to gauge market turning points.  

While not standalone, it enhances decision-making by reflecting crowd psychology and market extremes.
