What Is the Fear and Greed Index?

The Crypto Fear and Greed Index measures the overall sentiment and emotion of the cryptocurrency market.
It ranges from 0 to 100, where:

  • 0–24 = Extreme Fear (investors are very worried, often a buying opportunity)
  • 25–49 = Fear
  • 50–74 = Greed
  • 75–100 = Extreme Greed (market may be overheated or due for a correction)

This index helps traders understand whether investors are too fearful or too greedy, which can influence market movements.

How Is It Calculated?

The Fear and Greed Index is updated daily and combines several market indicators.
Here’s a breakdown of the main components (with their approximate weightings used by Alternative.me, one of the most popular sources):

  1. Volatility (25%)
    • Compares current volatility and drawdowns to the average of the last 30 and 90 days.
    • High volatility indicates fear in the market.
  2. Market Momentum and Volume (25%)
    • Measures trading volume and market momentum compared to recent averages.
    • High buying volume suggests greed.
  3. Social Media (15%)
    • Analyzes activity, hashtags, and engagement on platforms like X (formerly Twitter).
    • Rapid increase in mentions shows growing greed and hype.
  4. Surveys (15%)(currently paused)
    • Previously used community polls to gauge public sentiment.
  5. Bitcoin Dominance (10%)
    • When Bitcoin dominance rises, it signals fear (investors move to safer assets).
    • When it drops, it signals greed (investors move to riskier altcoins).
  6. Google Trends (10%)
    • Tracks search interest for Bitcoin-related terms.
    • More searches about “Bitcoin crash” = fear, while “how to buy Bitcoin” = greed.

All these factors are normalized into a single number between 0 and 100.

Data Sources

The index pulls data from multiple sources, including:

  • Market data providers (for price, volume, and volatility)
  • Social media APIs (Twitter/X trends and engagement)
  • Google Trends (search term frequency)
  • Bitcoin dominance charts (from platforms like CoinMarketCap or TradingView)

Conclusion

The Fear and Greed Index is a quick snapshot of the crypto market’s emotional state.
When the index shows extreme fear, investors are overly cautious — often a signal that the market could rebound.
When it shows extreme greed, optimism is high — which can mean prices are overextended.
Smart traders use this index as a sentiment guide, not a standalone trading signal.
