0 means extreme fear, 100 means extreme greed. It describes the mood of the market, not where the price goes next, and it is not a trade signal.
Data by alternative.me. The index is calculated by alternative.me from Bitcoin volatility, market momentum and volume, social media, dominance and search trends (the survey component is currently paused). It is updated once a day.
The Fear & Greed Index condenses the mood of the crypto market into one number from 0 to 100. Values near 0 mean extreme fear: investors are selling and worried. Values near 100 mean extreme greed: investors are buying aggressively and the market feels euphoric. This page shows today's value, how it changed over a day, a week and a month, a chart for the last year and a table of the last 30 days. The numbers come from alternative.me through its free public API, and the source is named next to every display.
According to its author, alternative.me, the index combines several factors: Bitcoin volatility and drawdowns (25%), market momentum and volume compared with the 30 and 90 day averages (25%), social media activity (15%), Bitcoin dominance (10%) and Google search trends (10%). A survey component (15%) is currently paused. The value is recalculated once a day. Because most of the inputs are tied to Bitcoin, the index describes the market as a whole, not one particular coin.
We use the same zones as the source: 0 to 24 extreme fear, 25 to 44 fear, 45 to 55 neutral, 56 to 75 greed and 76 to 100 extreme greed. The one-year chart shades the zones, so you can see how long the market stayed in each of them, and the block below the chart counts the days. Hover the line to see the value for any date. A long stay in one zone is normal: the index often remains in greed during a rising market and in fear during a falling one.
Sentiment is context. It does not say when a trend will end and it is not a buy or sell signal. We show it next to Radar and Liquidations so that you can see the mood of the market while you look at unusual activity on individual coins. We have not found that any single indicator on this site predicts price, and we test every idea on data before we rely on it.
There is no good or bad value. It measures mood: low values mean fear, high values mean greed. What you do with that is your own decision.
Once a day. The page refreshes the data from the source regularly, but the value itself changes daily.
No. Extreme fear only says that the market is scared. Prices can keep falling or recover, and the index does not tell which.
