What is the Fear & Greed Index?
The Crypto Fear & Greed Index is published daily by Alternative.me. It measures market sentiment on a scale from 0 (Extreme Fear) to 100 (Extreme Greed) using 6 data sources: volatility (25%), market momentum (25%), social media (15%), surveys (15%), Bitcoin dominance (10%), and Google Trends (10%).
The index was inspired by CNN's Fear & Greed Index for traditional markets. In crypto, it has proven to be a reliable contrarian signal: extreme fear has historically coincided with cycle lows, while extreme greed has preceded major corrections. Currently: -/100.
How is the Fear & Greed Index calculated?
The Fear & Greed Index is divided into 5 zones. Each zone reflects a distinct sentiment condition - and historically, the extremes have been the most actionable signals for contrarian investors.
Maximum panic. The crowd is selling. Historically, Extreme Fear has coincided with major cycle lows - the hardest time to act, often the most rewarding.
Below-average sentiment. Market uncertainty dominates. The crowd is nervous but not in full panic.
◂ Current zoneBalanced sentiment. No strong signal in either direction. On-chain data becomes the tiebreaker here.
Above-average optimism. FOMO starting to build. Risk appetite is rising - but so is risk.
Euphoria. The crowd is all-in. Historically, extended periods above 75 have preceded major corrections - often within weeks.
Fear & Greed is one signal. The BTC NHCI Score combines it with 36 others - on-chain, macro, and derivatives - so you get the full picture, not just the sentiment layer.

The BTC NHCI Score includes the Fear & Greed Index as one of its 37 indicators, but weights it carefully. Alone, sentiment can be misleading - markets can stay irrational for weeks. The NHCI combines it with on-chain data (MVRV, NUPL, aSOPR) and macro signals (M2, VIX) to filter noise.
A Fear & Greed reading of 23 (Fear) aligned with MVRV in the Accumulation zone and M2 expanding globally is a very different signal than Fear & Greed of 23 during a macro contraction. The NHCI Score reads all 13 inputs simultaneously so you don't have to.
Limitations of the Fear & Greed Index alone
The Fear & Greed Index is a useful sentiment gauge but has real limitations as a standalone signal. It reacts to price - meaning it often shows Fear AFTER a drop and Greed AFTER a rally. This makes it a lagging indicator when used in isolation.
It also doesn't distinguish between healthy bull market corrections (short-term Fear in a Bull zone) and genuine cycle tops (Greed in a Distribution zone). Without on-chain context, the signal is incomplete. This is why the NHCI Score combines it with 36 other indicators.
The current F&G reading is -/100. Combined with BTC NHCI Score of -/100, this gives a much more complete picture than either indicator alone.

- F&G measures sentiment from 0 (Extreme Fear) to 100 (Extreme Greed)
- Calculated from 6 sources: volatility, momentum, social, surveys, dominance, trends
- Extreme Fear has historically coincided with cycle lows
- Extreme Greed has preceded major corrections

After several full cycles, I read Fear & Greed as a mirror of the crowd, not a forecast. Extreme Fear has repeatedly marked the moments I was most glad I stayed exposed to Bitcoin; Extreme Greed is where I get careful about timing, never about the asset. The honest caveat: it lags price and can pin at an extreme for weeks, so I never act on it alone. I treat it as one voice inside the wider cycle, and let the full picture decide.

Extreme greed (75–100) signals that markets are overheated with speculative buying. It is a contrarian bearish signal - when everyone is greedy, risk is highest. Extreme greed frequently appears near Bitcoin cycle tops and precedes sharp corrections.
Is the Fear and Greed Index reliable on its own?
The Fear and Greed Index is useful as a sentiment indicator but should not be used alone. It reacts to price rather than predicting it, and can stay at extremes for weeks. NeverHodl includes it as one of 37 inputs in the NHCI Score - where it adds signal but cannot trigger an alert on its own.
