The Crypto Fear & Greed Index distills market sentiment into a single number from 0 to 100. At the extremes, 0 is maximum fear — the market is panicking — and 100 is maximum greed, where euphoria dominates. The index is computed daily from a basket of signals including price momentum, volatility, social volume, market dominance and survey data. It updates once per day.
The index is most useful as a contrarian signal and a regime marker. Sustained extreme fear has historically been a better entry environment than sustained extreme greed, because fear tends to accompany oversold conditions while greed tends to accompany overleveraged ones. But the index tells you where sentiment is, not where price is going — a greed reading can persist for weeks during a strong trend before it reverts.
Watching the 7-day and 30-day changes matters more than any single reading. A rapid shift from fear to greed in a week suggests a momentum swing; a slow drift from neutral toward greed over a month suggests accumulating risk appetite. The trend in sentiment is often more informative than the level.
The Crypto Fear & Greed Index is a daily 0–100 sentiment score for the crypto market. A reading near 0 means the market is in extreme fear; near 100 means extreme greed. It aggregates signals including price momentum, volatility, social media volume, Bitcoin dominance and market surveys into a single number.
The index is produced by Alternative.me and weights six factors: volatility (25%), market momentum and volume (25%), social media sentiment (15%), surveys (15%), Bitcoin dominance (10%), and search trends (10%). Each factor is normalized to a 0–100 scale before weighting.
Primarily as a contrarian and regime marker. Extreme fear has historically coincided with better buying opportunities; extreme greed has coincided with elevated risk of a reversal. The index does not predict price direction — it tells you where crowd sentiment sits, which you use as context alongside price action, funding rates and open interest.
Once per day. The reading shown here reflects the current day's value, with 1-day, 7-day, 30-day and 90-day change figures computed against the historical readings from those periods. The history chart covers up to 365 days.
