The Crypto Fear and Greed Index is a simple way to summarise how stretched sentiment looks at a glance. It scores the market from 0 (Extreme Fear) to 100 (Extreme Greed) so you can step back from headlines and check whether the crowd is panicking or piling in. Best Info Crypto runs its own index with a transparent, market-data-only methodology; you can follow it anytime on the Crypto Fear and Greed Index page, with factor breakdown and history on the same screen.
What Is the Fear and Greed Index?
The idea of a “fear and greed” gauge comes from traditional markets: one number that captures whether investors are defensive or risk-on. In crypto, that still maps to the same behaviour—fear shows up as selling, de-risking, and volatility spikes; greed shows up as FOMO, heavy volume on rallies, and rotation into higher-beta names. The opposite force — FUD, or fear, uncertainty and doubt — usually drags the gauge the other way.
It is not a crystal ball. It is a sentiment snapshot built from measurable inputs so you can compare today’s mood to recent weeks and see which drivers matter most.
How the Best Info Crypto Index Is Calculated
Our index uses four equally weighted factors (25% each), all computed from CoinGecko market data—Bitcoin price history, global market stats, and dominance—so there are no opaque social or survey layers mixed in. The headline score is the average of the four factor scores, each normalised to 0–100.
1. Volatility (25%)
We measure Bitcoin’s 30-day return volatility and compare it to a 90-day rolling baseline. Calm markets score toward greed; turbulent markets, especially after sharp drawdowns, score toward fear.
2. Market Momentum and Volume (25%)
We compare Bitcoin’s 7-day average volume to its 30-day average and blend that with the 7-day price return. Rising price on strong volume reads as greed; weak price action on thin volume often reads as fear or capitulation.
3. Bitcoin Dominance (25%)
Bitcoin’s share of total crypto market cap shows where capital is going. Falling dominance usually means rotation into altcoins—a greedier, risk-on posture. Rising dominance often means flight to BTC as the relative “safe” liquidity hub, which we score toward fear. You can see the raw dominance figure live on our market overview page.
4. Total Market Cap Trend (25%)
The 24-hour change in total crypto market cap captures broad risk-on or risk-off tone in one number. Expanding total cap pushes the factor toward greed; contracting total cap pushes it toward fear. The market overview page shows the same number alongside the biggest daily gainers and losers.
The live page recomputes these inputs on a schedule (roughly every 30 minutes), caches the result briefly, and shows now, yesterday, last week, and last month so you are not looking at a single frozen print.
The Five Sentiment Levels
The 0–100 scale is grouped into five labels. Thresholds match the live Fear and Greed page:
| Level | Score | What It Means |
|---|---|---|
| Extreme Fear | 0–24 | Panic and capitulation are common words here; sentiment and positioning are often washed out. |
| Fear | 25–44 | Cautious tone, selling pressure, or a market digesting bad news. |
| Neutral | 45–54 | Mixed signals, range-bound action, no strong crowd skew. |
| Greed | 55–74 | Risk-on behaviour, improving tone, FOMO building in pockets of the market. |
| Extreme Greed | 75–100 | Euphoric conditions, crowded longs, and higher odds of a sentiment snapback—not a timer, but a warning to stay disciplined. |
How to Use the Fear and Greed Index
As a Contrarian Indicator
Many investors use extremes as a contrarian sanity check, not an automatic trade: Extreme Fear when others are panicking, Extreme Greed when others are chasing. The edge, if any, is emotional—avoid selling lows and buying highs because the feed feels urgent.
Combine With Other Tools
Never rely on one indicator alone. Use it alongside:
- Technical analysis – Support and resistance, trend structure, RSI, moving averages
- On-chain data – Exchange flows, whale movements, stablecoin liquidity (where relevant)
- Fundamentals and news – Regulation, macro, protocol or ETF catalysts
- Cross-checks – Live prices, Bitcoin and Ethereum coin pages, and markets coverage
Avoid Timing the Market Perfectly
Extreme readings can persist. Fear can grind for weeks before a bottom; greed can run through a full leg of a bull market. Use the index to inform position sizing and patience, not to pick the exact hour of a reversal.
Dollar-Cost Averaging
If you invest on a schedule, stretches of Extreme Fear are often when sticking to the plan is hardest—and historically when long-term contributors have added at better average prices. Still, one print does not justify going all-in; keep risk in line with your plan. Our crypto converter makes it easy to see what a given fiat amount is in BTC or ETH at today’s price, and the portfolio tracker logs the cost basis of each buy so you can measure how DCA is actually performing over time.
Limitations
- Not predictive – Past behaviour around extremes does not guarantee the next move
- Model-specific – Different sites use different inputs; scores will not match one-for-one elsewhere
- BTC-centric inputs – Two factors are Bitcoin-specific; altcoin narratives can diverge
- Lag vs. headlines – The gauge reflects processed market data, not every intraday narrative spike
