The Crypto Fear and Greed Index is a popular market sentiment indicator that measures whether the crypto market is driven by fear (bearish) or greed (bullish) at any given time. The index ranges from 0 (Extreme Fear) to 100 (Extreme Greed).
How It's Calculated
The index aggregates data from multiple sources: - Volatility (25%): Current volatility vs. 30/90-day averages - Market Volume (25%): Current volume compared to historical averages - Social Media (15%): Sentiment analysis from Twitter, Reddit, Telegram - Surveys (15%): Periodic community polls - Bitcoin Dominance (10%): BTC's share of total crypto market cap - Google Trends (10%): Search volume for crypto-related terms
