## About

LunarCrush aggregates public posts from X (Twitter), Reddit, YouTube, TikTok, Instagram, and News into topics and categories, then scores them in real time. Every post is run through topic classification, spam/bot filtering, sentiment scoring, and creator weighting before it reaches a metric, so the numbers reflect cleaned, engagement-weighted activity rather than raw mention counts. Proprietary metrics include Galaxy Score™ (a 0–100 composite of social and market health) and AltRank™ (relative momentum across the market).
