Fear & Greed Index
A composite index of crypto market sentiment from 0 (extreme fear) to 100 (extreme greed).
What the metric shows
The Fear and Greed Index consolidates several market signals into a single number from 0 to 100. The idea is classic for any market: the majority buys in euphoria and sells in panic, so the extremes of the index usually mean a reversal.
Practice shows that the index is useful precisely at the edges of the scale. Values below 15 have happened rarely in history and almost always marked a bottom, values above 85 — local tops. Inside the range, the index simply follows the price and does not add information.
How it is calculated
How to read the signal
| Zone | Value | Interpretation |
|---|---|---|
| > 75 | Extreme greed — historically local top zones | |
| 25 – 75 | Neutral range, no signal | |
| < 25 | Extreme fear — historically buy zones |
