Why Measure Fear and Greed in Crypto Markets?
Cryptocurrency markets are driven by strong emotional reactions. Investors often exhibit greed during price surges, leading to FOMO (Fear of Missing Out), and fear during downturns, triggering panic selling. The Crypto Fear & Greed Index helps mitigate these emotional biases by providing objective sentiment analysis.
Key Principles of the Index:
- Extreme Fear suggests potential undervaluation, possibly signaling a buying opportunity.
- Extreme Greed may indicate an overbought market, hinting at an upcoming correction.
The index quantifies Bitcoin market sentiment on a scale of 0 (Extreme Fear) to 100 (Extreme Greed), synthesizing data from multiple sources to reflect real-time investor behavior.
How the Fear & Greed Index Is Calculated
The index evaluates Bitcoin sentiment (with altcoin indices planned) using weighted metrics:
1. Volatility (25%)
- Measures current price fluctuations and drawdowns against 30-day and 90-day averages.
- Elevated volatility often correlates with fearful markets.
2. Market Momentum & Volume (25%)
- Analyzes trading volume and price trends compared to historical averages.
- High buying volume in bullish markets suggests excessive greed.
3. Social Media Activity (15%)
- Tracks engagement rates for Bitcoin-related hashtags on Twitter.
- Surges in interactions indicate heightened public interest (greed).

4. Dominance (10%)
Bitcoin’s market cap share reflects risk appetite:
- Rising dominance = Safe-haven demand (fear).
- Declining dominance = Altcoin speculation (greed).
5. Google Trends (10%)
- Monitors search query spikes (e.g., "Bitcoin crash") to gauge fear.
- Example: A +1,550% rise in "Bitcoin price manipulation" searches (May 2018) signaled market anxiety.
