Sentiment Analysis

Response: {
value: "73",
value_classification: "Greed",
timestamp: "..."
}
| Score | Classification | What It Means |
|---|
| 0-24 | Extreme Fear | Market is scared — historically a buying signal |
| 25-49 | Fear | Caution prevails |
| 50 | Neutral | Balanced |
| 51-74 | Greed | Optimism rising |
| 75-100 | Extreme Greed | Euphoria — historically a selling signal |
Social Sentiment Sources
| Source | What It Measures | Access |
|---|
| LunarCrush | Social mentions, engagement, sentiment across Twitter/Reddit | Free tier API |
| Santiment | On-chain + social metrics, whale behavior | Free tier |
| Twitter/X | Raw social sentiment, CT narratives | API (paid) |
| Reddit | Community sentiment in crypto subreddits | Free API |
DIY Sentiment Scoring
A simple keyword-based approach:
Bullish signals:
- "breakout", "ATH", "accumulate", "undervalued", "adoption"
- Large whale buys, exchange outflows, increasing TVL
Bearish signals:
- "crash", "dump", "sell", "overvalued", "FUD"
- Exchange inflows, declining TVL, developer departures
Neutral/noise:
- "partnership", "listing" (often priced in)
- "soon", "moon" (low-quality signal)
News Filtering Strategies
Signal vs Noise
| Signal (Act On) | Noise (Ignore) |
|---|
| Regulatory rulings (SEC, EU) | Rumors without sources |
| Protocol hacks/exploits | "Price prediction" articles |
| Major protocol upgrades | Influencer shill posts |
| Institutional adoption news | Recycled news from 3 days ago |
| Governance votes (on-chain) | "Top 10" listicles |
Category-Based Filtering
| Category | Keywords | Relevance |
|---|
| Regulatory | SEC, ruling, ban, legal, compliance | High for portfolio |
| Security | hack, exploit, vulnerability, drain | Urgent — may need action |
| Protocol | upgrade, fork, launch, migration | Medium — affects operations |
| Market | ATH, crash, whale, volume | Context-dependent |
| DeFi | yield, TVL, liquidity, farming | Relevant for DeFi users |
Time-Based Filtering
Most crypto news follows a pattern:
- 00:00-06:00 UTC: Asian market news (Korea, Japan regulatory, Binance updates)
- 06:00-12:00 UTC: European market news (EU regulations, DeFi governance)
- 12:00-18:00 UTC: US market news (SEC, institutional, macro)
- 18:00-00:00 UTC: US afternoon + evening social activity (CT narratives)
Building a Daily Briefing
A structured daily crypto briefing should include:
📊 MARKET SNAPSHOT
- BTC price + 24h change
- ETH price + 24h change
- Fear & Greed Index
- Total DeFi TVL (via DeFi Llama)
📰 TOP HEADLINES (3-5)
- Filtered by relevance and engagement
- Source attribution
🔥 HOT TOPICS
- Trending tokens/protocols
- Active governance votes
⚡ DeFi PULSE
- Yield changes (notable APY movements)
- Protocol TVL changes >10%
- New protocol launches
🔐 SECURITY ALERTS
- Any hacks or exploits in last 24h
- Critical vulnerability disclosures
SperaxOS generates automated daily briefings with this exact structure using its builtin daily-report tool — combining CryptoPanic, DeFi Llama, and Fear & Greed data.
Agent Tips
- Aggregate multiple sources — never rely on one news feed
- Prioritize security news — hacks and exploits require immediate attention
- Filter by engagement — high-vote CryptoPanic posts are usually more relevant
- Check timestamps — crypto moves fast, stale news can be misleading
- RSS is underrated — free, reliable, no API limits
- Fear & Greed as contrarian indicator — historically, extreme fear = good entry, extreme greed = caution
- Sperax-specific: Monitor USDs/SPA mentions for ecosystem updates
