The crypto Fear and Greed Index is a sentiment index: a single number, from 0 to 100, that sums up the mood of the market. Its publisher, the website alternative.me, describes it this way: each day, it analyzes emotions and sentiment from several sources and crunches them into one number. Zero means "Extreme Fear" and 100 means "Extreme Greed".
Two details the publisher's page states itself and that are easy to forget. The current index is computed for bitcoin only: separate indices for large altcoins are announced there for later. And it is a daily value, published with a class in plain words (Extreme Fear, Fear, Neutral, Greed, Extreme Greed), which the block above displays without recomputing it.
Whether you call it fear and greed, fear vs greed or the index of fear, it is the same number. It is not a price measure, it is a mood measure, and it should be read as one.
The number runs from 0 to 100: the lower it is, the more fearful the market is described to be, the higher it is, the greedier. The class written next to it, from "Extreme Fear" to "Extreme Greed", is the one the publisher returns, not this page's interpretation.
A single value says little. The three reference points and the bars for the last 30 days show whether sentiment is rising, falling or flat, and how long it has stayed in the same zone.
The index covers bitcoin and blends volatility, volume, social media, dominance and search trends. It describes a mood, once a day. It says neither where price will go nor what you should do with your position.
In one sentence: a number from 0 to 100, published every day by alternative.me, computed for bitcoin from several weighted sources, where 0 stands for extreme fear and 100 for extreme greed.

Read the fear and greed guide →The publisher's page lists the factors that go into the index and the weight of each. Here they are as the page gives them, with nothing added.
| Component | Weight | What it measures, according to the publisher |
|---|---|---|
| Volatility | 25% | Bitcoin's current volatility and maximum drawdowns, compared with their 30-day and 90-day averages. An unusual rise in volatility is read there as a sign of fear. |
| Market momentum and volume | 25% | Market volume and momentum, also compared with the 30-day and 90-day averages. High buying volumes in a rising market are read there as greed. |
| Social media | 15% | The number of posts on certain hashtags and how fast they collect interactions. An unusually high interaction rate is read there as greed. |
| Surveys | 15%, paused | Weekly polls of crypto investors. The page marks them "currently paused". |
| Dominance | 10% | Bitcoin's share of the total crypto market cap. Rising dominance is read there as fear, shrinking dominance as greed. |
| Search trends | 10% | Google Trends data for bitcoin-related queries, especially the change in search volumes. |
Three details from that same page are worth reading before leaning on the number. The text speaks of five sources and the list has six lines, including the surveys, marked as paused. It does not say how the surveys' weight is handled during that pause. And it states that the Reddit analysis is not yet part of the published index: only the Twitter one is running.
In practice: the index is a construction, with source and weight choices made by its publisher. Two sentiment indices built differently can show two different numbers on the same day without either being wrong.
The publisher explains why it measures fear and greed. In its words, the crypto market is very emotional: people get greedy when it rises, which feeds FOMO, and they often sell in reaction to seeing red numbers.
It then sets out two assumptions, and that is its own word: "two simple assumptions". Extreme fear can be a sign that investors are too worried, which could be a buying opportunity. And when investors are getting too greedy, the market would be due for a correction.
These are reading assumptions, not results. The page publishes no test of what followed past extremes, and it ends with an unambiguous disclaimer: nothing on it is investment advice. This page goes no further than its source.
There is another index with the same name, published by CNN, and the two should not be mixed up. That one covers the stock market: its page presents it as a way to gauge stock market movements and whether stocks are fairly priced.
It is built differently. According to the CNN page, it compiles seven stock market indicators (market momentum, stock price strength, stock price breadth, put and call options, junk bond demand, market volatility and safe haven demand), each with equal weighting, into a score from 0 to 100. It is recalculated as soon as new data becomes available, whereas the crypto index shown here is daily.
The two share a scale and an idea, not a method or a market. A reading on one does not carry over to the other: an index is compared with its own history.
Four things people read into it that it does not contain.
A sentiment index from 0 to 100 published every day by alternative.me. Zero stands for extreme fear, 100 for extreme greed. It is computed for bitcoin from several sources: volatility, momentum and volume, social media, dominance and search trends.
According to its publisher, by weighting factors: volatility 25%, market momentum and volume 25%, social media 15%, surveys 15% (marked as paused), bitcoin dominance 10% and search trends 10%. Its page does not publish the formula beyond that description.
Once a day. The publisher's page shows a countdown to the next update, and the value shown here carries its date. Between two updates, the number does not move.
No. The publisher states that the current index is for bitcoin only, and announces separate indices for large altcoins for later. Reading it as the mood of one specific altcoin makes it say something it does not measure.
No. The stock market index is published by CNN, covers the stock market and compiles seven equally weighted indicators. The crypto index shown here is published by alternative.me and covers bitcoin. Same name, same 0 to 100 scale, two methods and two markets.
That is not what it is. The publisher sets out two reading assumptions about the extremes and reminds readers on the same page that nothing it publishes is investment advice. The index describes a sentiment: it gives no entry point, no target and no guarantee.
