Coin Fear and Greed Index

A crypto Fear and Greed Index is a composite sentiment gauge, commonly shown on a scale from 0 to 100. Lower readings tend to describe more fearful or defensive market behavior, while higher readings point to more enthusiastic or risk-seeking behavior.

Providers use different formulas, labels, and market coverage. Inputs may include volatility, price momentum and volume, social activity, search interest, market composition or dominance, derivatives, and sometimes surveys. The index describes apparent market mood, not an asset's intrinsic value, and it is not a reliable price forecast or buy/sell signal.

For useful context, compare readings over time within the same provider and combine them with broader research. Methodology examples from Alternative.me and CoinMarketCap illustrate why readings from different providers should not be assumed to be directly comparable.
