How to read the Crypto Fear & Greed Index
The index published by Alternative.me compresses several Bitcoin-market sentiment inputs into a 0–100 score. It describes a methodology-specific sentiment state; it is not a valuation model or a standalone trading signal.
In this guide
What the score represents
The publisher combines volatility, momentum and volume, social activity, Bitcoin dominance, and search trends. Its survey component is currently paused, so users should rely on the publisher's current methodology rather than an old fixed-weight summary.
This crypto index is separate from similarly named equity-market indices and the values are not interchangeable.
A disciplined use
Treat extreme values as context for positioning and risk appetite, then test the rule over a defined sample and holding period.
An extreme reading can persist. Combine it with price trend, volatility, liquidity, and explicit risk limits rather than buying or selling from the score alone.
Frequently asked questions
Does extreme fear guarantee a market bottom?⌄
No. It indicates stressed sentiment under this methodology, not the timing of a reversal.
Is this the CNN Fear & Greed Index?⌄
No. The publishers, markets, components, and calculations differ.
