Abstract
This paper examines the psychological drivers behind the meteoric rise and sudden crashes of "meme coins," a class of digital assets propelled not by fundamental value but by internet culture and social dynamics. We explore the roles of Fear of Missing Out (FOMO), herd behaviour, social proof, and dopamine‐reward loops in shaping investor decisions. A case study of the $TRUMP coin illustrates how manipulatory social media campaigns and influencer endorsements can decouple price movement from traditional valuation models. The analysis is based on a secondary review of academic articles, legal statements, and market research reports.
