Crypto Fear & Greed Index vs Bitcoin Price
The Crypto Fear & Greed Index summarises market psychology on a 0–100 scale. Overlaid on Bitcoin's log-price, the pattern is clear: extreme readings often precede a reversal. Use this to gut-check conviction — buy when others are fearful, trim when they're greedy.

Reading the bands
What each F&G zone means
0 – 25 · Extreme Fear
Capitulation territory
Investors are panicked, headlines are bearish, prices have usually pulled back ≥30% from recent highs. Historically this band has lined up with intermediate-term bottoms more often than not.
Contrarian setup: scale in, don't chase.
25 – 75 · Mixed
No sentiment edge
The most common reading. In this band, trend and structure matter more than sentiment. Don't try to fade noise — let other signals (price action, on-chain flows, macro) lead.
Sentiment-neutral: defer to trend.
75 – 100 · Extreme Greed
Late-cycle pop
Headlines are euphoric, retail interest spikes, leverage builds up across exchanges. Not a market top in itself — sentiment can stay euphoric for weeks — but a clear reason to tighten risk.
Reduce risk, look for bearish divergences.
Background
How the Fear & Greed index works
The Crypto Fear & Greed Index is published daily by alternative.me. It combines five inputs into a single 0–100 score: Bitcoin price volatility (25%), market momentum and volume (25%), social media activity (15%), survey results (15%, currently paused), Bitcoin dominance (10%), and Google Trends data (10%).
The output is intentionally simple: a single number that summarises whether the market is fearful (low) or greedy (high). Like any aggregate, it loses nuance — but its directional signal has been useful at extremes.
The key insight: markets reach extremes because the underlying conditions are extreme. By the time F&G prints below 25, prices have usually already corrected sharply; by the time it prints above 75, prices have already rallied. So F&G is more confirmation than leading indicator.
The best use is as a discipline tool. When F&G is in the high-greed zone, the index is reminding you that the easy money has likely been made and you should rebalance. When it prints extreme fear, it's reminding you that this is when the next leg of opportunity usually shows up — even if it doesn't feel like it.
FAQ
Fear & Greed Index — frequently asked questions
How is the Fear & Greed Index calculated?
It's a weighted average of five inputs: Bitcoin price volatility (25%), market momentum and volume (25%), social media activity (15%), Bitcoin dominance (10%), Google search Trends (10%). The survey component (15%) is currently paused. The result is normalised to a 0–100 scale where 0 = maximum fear and 100 = maximum greed.
How accurate is the index at predicting reversals?
Extreme readings (<20 or >80) have historically aligned with intermediate-term turns, but the timing is loose — the index can stay extreme for weeks before the market actually pivots. Treat it as confirmation of conditions, not a precise timing signal.
Should I use Fear & Greed as a buy/sell signal?
Not on its own. The index is best used as a sanity check on your own positioning — buying when F&G is in extreme fear is a contrarian discipline that has worked historically. But combine it with other inputs (price levels, on-chain data, macro context) before acting on it.
How often does the index update?
Once per day, typically by mid-morning UTC. The Daily Coins caches the latest value and refreshes within the hour. The chart above plots daily readings going back 12 months.
Is there a Fear & Greed index for individual coins?
The public alternative.me index is BTC-focused (because Bitcoin dominance is an input). For altcoins, sentiment is typically read from coin-specific social activity and price action — both of which feed into our individual coin prediction models.

Historical context
What every Fear & Greed extreme has actually meant
The Fear & Greed Index becomes much more useful once you have seen which past extremes coincided with which historical moments. The list below covers every reading above 90 and every reading below 15 across the index's available history, with what Bitcoin did in the 90-day and 365-day windows that followed.
Extreme Fear readings (≤15) and what came next
- February 28, 2019 — reading 5. Bitcoin at $3,820 just three months after the Bakkt-launch crash. BTC was up 165% within 365 days.
- March 13, 2020 — reading 8. Pandemic capitulation, BTC at $4,970. The index hit 8 the day after the lowest weekly close. BTC was up 590% within 365 days.
- June 19, 2022 — reading 6. Three Arrows Capital insolvency, Celsius freeze, Bitcoin at $17,800. BTC was up 150% within 365 days; the November 2022 FTX collapse extended the drawdown before the recovery began.
- November 9, 2022 — reading 10. FTX collapse day. Bitcoin at $15,600. This was the cycle bottom and BTC was up 220% within 365 days.
- January 2024 — reading 12 cluster. Pre-ETF-approval anxiety, BTC sub-$40k. ETFs launched ten days later; BTC was up 80% within 90 days.
The pattern is consistent: every reading below 15 in the index's history has produced a positive 365-day return on Bitcoin, and four out of five produced strongly positive 90-day returns as well. This is not a guarantee — small samples are dangerous — but it is one of the cleanest historical signals available to a retail trader.
Extreme Greed readings (≥90) and what came next
- February 17, 2021 — reading 95. The all-time-high cycle, BTC at $52,000 on the way to $64,000. BTC was down 36% within 90 days; the cycle peak printed in November.
- October 21, 2021 — reading 84. Pre-cycle-top euphoria, BTC at $66,000. The cycle peak printed a week later; BTC was down 22% within 90 days and 53% within 365 days.
- March 13, 2024 — reading 90. Post-ETF-approval melt-up, BTC at $73,000. BTC pulled back 18% within 60 days.
The Extreme Greed signal is less reliable than Extreme Fear because the market can stay euphoric for months — late-cycle bull markets routinely sustain 80–90 readings for weeks while prices keep climbing. The correct usage is as a "trim risk, take partial profits" signal, not a "sell everything" signal.
How institutions actually use sentiment data
Quant desks and crypto funds treat Fear & Greed less as a standalone signal and more as one of six or eight inputs to a regime-classification model. The index is most useful when stacked with on-chain MVRV ratio, perpetual-futures funding rates, and stablecoin supply ratio — when all four agree, the signal-to-noise ratio is materially higher than any single indicator. Retail traders can replicate the institutional approach by checking sentiment alongside the whale-tracker net-flow and the halving-cycle position — when those three signals align, conviction can rise; when they conflict, sizing should fall.
