What is the Crypto Fear & Greed Index?

The Crypto Fear & Greed Index is a composite sentiment indicator that analyzes multiple data sources to gauge the emotional state of the cryptocurrency market. It operates on a simple but powerful principle: when investors are driven by 'fear,' prices may be undervalued, presenting potential buying opportunities. Conversely, when 'greed' dominates, markets may be overextended and due for a correction. By providing a single, easy-to-understand number (0-100), it distills complex market psychology into a tactical tool for traders of all levels.

Key Features of the Fear & Greed Index

Multi-Factor Analysis

The index isn't based on a single metric. It synthesizes data from volatility, market momentum/volume, social media sentiment, surveys, and Bitcoin dominance to create a robust and holistic view of investor psychology, reducing the noise from any single source.

Historical Data & Charts

View sentiment trends over daily, weekly, monthly, and yearly timeframes. Historical charts are invaluable for backtesting sentiment extremes against major market tops and bottoms, providing context for the current reading.

Even crypto newcomers can use it to understand the prevailing market mood beyond just price charts.
