What it measures
Crowd sentiment — extremes have historically marked cycle turning points.
The Crypto Fear & Greed Index compresses market sentiment into a single 0–100 score: 0 is maximal fear, 100 maximal greed. It blends volatility, momentum, volume, social-media activity and Bitcoin dominance into one daily reading — a thermometer for how the crowd feels, not for what the market is worth.
How to read it
Sentiment is a contrarian tool at its extremes and noise in the middle. Readings under 25 have historically coincided with capitulation phases in which long-term buyers accumulated; readings above 75 mark euphoria, which is where cycles have tended to become fragile. Between roughly 40 and 60 the index says little — treat it as one input, never a signal on its own.
| 0 – 24 | Extreme fear — historically where accumulation happened |
| 25 – 44 | Fear — sentiment below neutral |
| 45 – 55 | Neutral |
| 56 – 75 | Greed — optimism is priced in |
| 76 – 100 | Extreme greed — historically fragile territory |
Frequently asked questions
What does the Crypto Fear & Greed Index measure?
It aggregates several market signals — volatility, momentum and volume, social-media activity, and Bitcoin dominance — into one daily 0–100 sentiment score for the crypto market. Low values mean the crowd is fearful, high values mean it is greedy.
Is a low Fear & Greed reading a buy signal?
Not by itself. Extreme fear has historically coincided with good long-term entry zones, but sentiment can stay depressed for months while prices keep falling. Long-term investors use it as context alongside valuation gauges like MVRV or the Mayer Multiple, not as a trigger.
