The Crypto Fear & Greed Index, Explained for Investors

The Crypto Fear & Greed Index compresses market sentiment into a single 0–100 reading: 0 is maximum fear, 100 is maximum greed. It blends volatility, momentum, trading volume, social media activity, bitcoin dominance and search trends into one number that is easy to track daily — you'll find the live reading on the CoinClass indicator board.

How to interpret the bands

Readings below 25 mark extreme fear — historically these have clustered near local bottoms, when forced sellers dominate and spot buyers are scarce. Readings above 75 mark extreme greed, typical of late-stage rallies driven by leverage and retail momentum. The middle band, roughly 40 to 60, is noise: sentiment there tells you little.

The index is a contrarian tool, not a timing signal. Extreme fear can persist for weeks in a genuine bear market, and extreme greed can persist through an entire parabolic advance. Desks use it as a position-sizing input — trimming into sustained greed, accumulating into sustained fear — rather than as a trade trigger.

Pairing sentiment with flows

The most informative setups appear when sentiment and institutional flows diverge. Extreme fear alongside continued ETF net inflows suggests retail capitulation into institutional accumulation. Extreme greed with flat or negative ETF flows suggests a rally running on leverage rather than new capital — historically a fragile configuration.
