Fear and Greed Index
What does a 0–100 crypto sentiment score combine, and which provider's method sits behind it?
Open the Social Sentiment dashboard
The Crypto Fear and Greed Index compresses several sentiment and market inputs into a score from 0 to 100. Lower scores indicate fear; higher scores indicate greed.
There is no universal formula. Alternative.me, CoinMarketCap and other providers use different inputs and weights, so the page must name the source behind the OCM chart.
What goes into the index
Alternative.me’s published Bitcoin methodology uses volatility, market momentum and volume, social media activity, Bitcoin dominance and Google Trends; its survey input is currently paused. Other providers use different blends, including derivatives and proprietary data.
Many inputs are related to price, but not all are produced by price alone. The index is best treated as a summary of the provider’s chosen sentiment proxies.
Why the provider matters
Two indices with the same name can produce different scores on the same day because the source data, weights and eligible assets differ. A score without attribution is therefore incomplete.
Methodology can also change. Keep the source link close to the chart and record any material change in the page’s update note.
Where the index helps
The score is useful for quickly locating sentiment within its recent range and spotting persistent extremes. It is less useful as a standalone forecast because fear can deepen and greed can persist.
Neutral readings are not worthless, but they are usually less distinctive. Duration, rate of change and disagreement with price can add more context than the number alone.
How to read it
Extreme greed. The provider’s inputs sit near the optimistic end of their range.
Greed. Sentiment and momentum inputs lean positive.
Neutral. The composite has no strong directional lean.
Fear. Risk and sentiment inputs lean defensive.
Extreme fear. The provider’s inputs sit near the pessimistic end of their range.
The Fear and Greed Index updates daily inside the Social Sentiment dashboard. The chart should display its provider and methodology link.
Common questions
Is extreme fear a buy signal?
No. It describes a sentiment condition that can persist while price keeps falling. Use it with valuation, liquidity and trend.
Why does it often track price?
Volatility, momentum and volume are direct inputs in common versions, while social and search activity often respond to market moves.
What does a neutral score tell me?
The composite is near the middle of its range. Changes in direction or a divergence from price may be more useful than the level.
Which Fear and Greed Index is this?
That must be stated on the chart. Providers use different data and weights, so the name alone is not enough.
How long should an extreme last?
There is no fixed rule. Persistence can make an extreme more meaningful, but it still does not determine the timing of a reversal.
