Crypto Fear & Greed Index

The Crypto Fear & Greed Index is a composite sentiment indicator that measures the overall emotional state of the cryptocurrency market on a scale from 0 (Extreme Fear) to 100 (Extreme Greed). It combines five weighted factors — volatility, market momentum/volume, social media sentiment, Bitcoin dominance, and search trends — to produce a single score that reflects whether investors are generally fearful or greedy.

The index uses five components: Volatility (25%) compares recent price swings to longer-term averages; Market Momentum & Volume (25%) looks at buying/selling pressure and trading volume relative to recent averages; Social Media (15%) gauges community sentiment and engagement; BTC Dominance (10%) tracks Bitcoin's share of total crypto market cap as a risk indicator; and Search Trends (25%) measures public interest via search momentum. Each component produces a 0-100 score, and the weighted average gives the final index value.

An Extreme Fear reading (0-20) means investors are very worried and selling aggressively. While this reflects a negative market outlook, contrarian investors often see extreme fear as a potential buying opportunity. The logic is that when sentiment hits rock bottom, much of the selling may already be done, and a recovery could follow. However, extreme fear can also persist during prolonged bear markets.

An Extreme Greed reading (81-100) indicates that FOMO (Fear Of Missing Out) is dominating the market. Everyone seems bullish and prices are often rising rapidly. While greed can sustain rallies, extreme greed has historically been a warning sign that the market may be overheated and due for a correction. It suggests that many potential buyers are already invested, leaving fewer new buyers to drive prices higher.

Our Fear & Greed Index is updated every 10 minutes using live data from the CoinGecko API. The page automatically refreshes to show the latest score. Because market sentiment can shift quickly — especially during high-volatility events — frequent updates ensure the reading reflects current conditions rather than stale data.

While the Fear & Greed Index can be a useful contrarian indicator, it should never be the sole basis for investment decisions. Extreme Fear has historically preceded recoveries, and Extreme Greed has preceded corrections — but timing these turns is extremely difficult. The index is best used as one input among many, alongside fundamental analysis, technical indicators, and your own risk tolerance and investment timeline.

Our index uses a similar concept but calculates the score independently using publicly available data from CoinGecko and price-derived metrics. The methodology weights may differ, and our data sources are fully transparent. We use real-time CoinGecko market data for volatility, momentum, volume, and BTC dominance calculations, with price momentum as a proxy for social and trend signals.
