### Sentiment Baseline Anchoring
When conducting qualitative sentiment analysis on news headlines or on-chain flows, first fetch the Fear & Greed index to anchor your assumptions about retail psychology.

1. If `value` < 25 (Extreme Fear): The market is highly sensitive to bearish catalysts. Price may be artificially depressed.
2. If `value` > 75 (Extreme Greed): The market is euphoric and ignoring risk. High danger of sudden liquidations or corrections.
