Sentiment Methodology

The actor uses a keyword-based approach with a curated crypto-specific lexicon:

• Positive terms (40+): bullish, moon, rocket, pump, buy, hodl, adoption, partnership, breakout, ath, etc.
• Negative terms (40+): bearish, dump, crash, sell, fud, scam, rug pull, rekt, liquidated, etc.

Each post is scored as: (positive_count - negative_count) / (positive_count + negative_count), normalized between -1 and +1.
