The Crypto Fear and Greed Index is a composite sentiment gauge, scored from 0 (extreme fear) to 100 (extreme greed), built from inputs like volatility, market momentum, social media activity, surveys, and bitcoin dominance. Alternative.me is a widely cited public source for the index.
Some traders use extreme readings as a contrarian signal — the idea that markets often overshoot at emotional extremes — but the index summarizes mood, not fundamentals, and there's no guarantee that "extreme fear" marks a bottom or "extreme greed" marks a top on any given day. It's best understood as one snapshot of crowd psychology among many possible inputs.
