Understanding the Crypto Fear & Greed Index
The Crypto Fear and Greed Index is an analytical tool measuring prevailing market sentiment in cryptocurrency trading. This comprehensive index synthesizes multiple indicators to reveal the market's emotional state:
Key Components (Weighted Indicators)
Volatility (25%)
Measures price fluctuation intensity in crypto markets:- High volatility → Fear (market uncertainty)
- Low volatility → Greed (investor confidence)
Market Momentum/Volume (25%)
Tracks trading volume and price trends:- Rising volume + positive trends → Greed
- Declining volume + negative trends → Fear
Social Media Sentiment (15%)
Analyzes discussions on platforms like Twitter and Reddit:- Positive/active engagement → Greed
- Negative/passive conversations → Fear
Surveys (15%)
Direct investor polling reveals:- Bullish responses → Greed
- Bearish responses → Fear
Dominance (10%)
Bitcoin's market share indicates:- High dominance → Fear (safe-haven preference)
- Low dominance → Greed (altcoin speculation)
Using machine learning algorithms, the index compiles these metrics into a 0-100 score, where higher values signal greed and lower values reflect fear.
