Tips

• Use --sentiment flag on top and pulse for more accurate scores (adds ~2 min)
• Without --sentiment, social score defaults to 50 (neutral) — technicals only
• Use --no-crypto to exclude crypto assets from scans
• Schedule python3 ripe-scan.py snapshot --sentiment via cron for daily tracking
• Compare with changes to catch breakout transitions early
