Crypto Fear & Greed Index
The Fear & Greed Index measures market sentiment on a 0–100 scale. Coingulp shows the current value and 30 days of history so you can spot emotional extremes.
What it is
The Fear & Greed Index is a popular indicator of crypto market sentiment. It converts emotions of market participants into a single number from 0 (extreme fear) to 100 (extreme greed). Coingulp takes the data from alternative.me and shows the current value plus the last 30 days of history.
- 0–24: extreme fear — panic selling, low prices, but often the zone of best entry points
- 25–49: fear — caution prevails, the market is under pressure
- 50–74: greed — optimism, growing activity
- 75–100: extreme greed — euphoria, the zone of the highest correction risk
How it is calculated
The index is a composite of several factors that measure the mood of the market, each with its own weight:
- Volatility (25%) — sharp price moves increase fear
- Market momentum/volume (25%) — comparison of current volume with the 30/90-day average
- Social media (15%) — the tone of mentions of crypto in social networks
- Surveys (15%) — voting among market participants
- Dominance (10%) — the share of BTC in the total market cap
- Google Trends (10%) — search interest in Bitcoin
How to use it
- 1. Open /fear-greed and look at the current value and the label (Fear / Greed / Extreme ...)
- 2. Scroll the 30-day history: is the index falling, growing or sideways?
- 3. Compare the index with the price: if prices are falling and fear is growing — the market is closer to capitulation
- 4. Use extremes as a context for your own decisions, not as an automatic signal
A practical example
The index has dropped to 18 (extreme fear) after a sharp fall, and Bitcoin is down 20% from the highs. Historically, such zones have often been good entry points for long-term positions — because most weak hands have already sold. Conversely, a value of 88 (extreme greed) after a long rally usually means that the market is overheated and the risk of a correction is high.
Tips
- The index is a sentiment gauge, not a price forecast — always combine it with your own analysis
- Pay attention to the dynamics: a fast drop from 60 to 20 is a stronger signal than a slow decline
- In extreme greed, take profits in parts; in extreme fear, do not rush to sell everything
- Data source: alternative.me — attribution is required when republishing the index

FAQ
What does 0 and 100 mean?
0 means extreme fear — panic and mass selling, prices are usually under pressure. 100 means extreme greed — euphoria and maximum optimism, which historically often precedes corrections.
Where does the data come from?
Coingulp takes the index from alternative.me, which calculates it from volatility, market volume, social media tone, surveys, BTC dominance and Google Trends.
How often is the index updated?
The index is calculated daily. Coingulp caches the data and shows the current value plus the last 30 days of history.
Is the index a buy or sell signal?
No. It is a contrarian context indicator: extremes often coincide with local bottoms or tops, but the index alone is not enough for a decision.
