How the Crypto Fear & Greed Index is calculated
The 6 factors behind the index
The crypto Fear & Greed Index is a composite indicator developed by Alternative.me that aggregates six distinct data sources to synthesize market sentiment into a single number from 0 to 100. It is not based on Bitcoin's price — it measures the emotional behavior of investors instead.
Volatility accounts for 25% of the weight: when BTC price shows abnormal swings compared to the 30 and 90-day averages, the index shifts toward fear. Market momentum (25%) compares current buying volume to historical averages — high volume in an uptrend signals greed. Social media sentiment (15%) analyzes posts and interactions on Twitter and Reddit related to cryptocurrencies.
Bitcoin dominance (10%) measures BTC's share of total market capitalization: when it rises, investors seek safety (fear); when it falls, they chase returns on altcoins (greed). Finally, Google Trends (10%) tracks global searches for terms like "Bitcoin price crash" or "crypto bull run". Together, these six signals give a reliable picture of collective market psychology.
How to use the Fear & Greed Index in crypto trading
Buy the fear, sell the greed
Warren Buffett's famous phrase — "be fearful when others are greedy, and greedy when others are fearful" — has shown some historical validity in crypto markets. Major bottoms are often preceded by or coincident with Extreme Fear readings (0–24), while local tops tend to form when the index exceeds 75.
This doesn't mean the Fear & Greed Index is a precise predictive tool: markets can remain irrational longer than you can remain solvent. Its real utility is as a context filter. If your trading system generates a buy signal when the index is at 15, you have additional confirmation. If it generates a buy when the index is at 90, extra caution is warranted.
Saturia integrates the Fear & Greed Index into its Pulse AI™ in exactly this way: as one of 20+ signals that contribute to the final assessment, weighted according to the current market regime. The result is a clear directional signal — BUY/SELL, LONG/SHORT — with the AI's confidence level.
