FAQFrequently asked questions
What is the Crypto Fear & Greed Index?
The Crypto Fear & Greed Index is a single 0–100 score that summarizes the overall emotion of the crypto market. A low score means fear (investors are worried and selling), while a high score means greed (investors are optimistic and buying). As of July 4, 2026, Ruma’s index reads 28 — Fear.
How is Ruma’s Fear & Greed Index calculated?
Ruma combines five factors into one score: social sentiment (LLM-scored from every relevant post), social interest (attention volume), price momentum, volatility, and emotional intensity across a 15-emotion model. Social signals are weighted heavily because Ruma is built on social intelligence rather than price alone.
Is high greed bad?
Not inherently, but extremes are contrarian signals. Historically, Extreme Greed (above 80) has often preceded market corrections, while Extreme Fear (below 20) has marked undervaluation and buying opportunities. The index is a sentiment gauge, not financial advice.
How often is the index updated?
Ruma refreshes the Crypto Fear & Greed Index continuously as new social data arrives, and this page updates hourly.
Does Ruma have a Fear & Greed Index for altcoins?
Yes. Unlike indexes that only cover Bitcoin, Ruma computes a per-token Fear & Greed Index across 100,000+ tokens, so you can see sentiment for any specific coin — not just the overall market.
