Understanding the Fear and Greed Index
The Fear and Greed Index, originally developed by CNN Business for stock markets, measures market sentiment on a scale from 0 (extreme fear) to 100 (extreme greed). Alternative.me later adapted this concept for cryptocurrencies, creating the Crypto Fear and Greed Index, which helps investors gauge collective market psychology.
Key Objectives of the Index
- Market Sentiment Analysis: Identifies emotional extremes that often precede price reversals.
- Strategic Decision-Making: Helps traders time entry/exit points by highlighting overbought (greed) or oversold (fear) conditions.
- Risk Management: Flags potential bubbles or undervalued assets through quantifiable metrics.
Leveraging Market Uncertainty
- Fear Zones (0–49): Indicate undervaluation, presenting buying opportunities during "blood in the streets" scenarios.
- Greed Zones (50–100): Signal overvaluation, suggesting caution or profit-taking before corrections.

Interpreting Extreme Market Sentiments
| Sentiment Level | Index Score | Market Implications | Actionable Insight |
