What it is

The Crypto Fear & Greed Index condenses several sentiment inputs — volatility, momentum, social media, surveys and more — into one 0–100 number. 0 = extreme fear, 100 = extreme greed.

Why it is contrarian

Crowd emotion peaks at exactly the wrong moments. Extreme fear (single digits) has clustered around cycle bottoms; extreme greed (90+) has clustered around tops. The uncomfortable trade is usually the historically rewarded one.

What it is telling us now

Today’s reading is shown live above and on the dashboard. But sentiment alone is noisy day to day — which is why it is only 20% of the ARC Index.

ARC uses Fear & Greed as a contrarian tilt, balanced against trend, drawdown and liquidity — so a single emotional spike doesn’t drive your decision.

Fear or greed — where are we now?

Sentiment is one of four signals in the ARC Index. See the full read.
