Fear & Greed Index Beginner
The Fear & Greed Index boils crypto market sentiment down to a single 0–100 score, from extreme fear to extreme greed.
It rolls signals such as volatility and momentum into one figure. Treat it as a mood gauge for context — not a trading signal, and certainly not financial advice.
This definition is educational and not financial advice. Crypto is volatile and high-risk — always do your own research.
