The Solana-based meme coin 'Scam Altman' (SCAM) briefly surpassed a $10 million market cap within eight hours of its launch, before slightly retracing to $9.82 million. Trading volume for SCAM reached $19.6 million during this period. The coin's rapid rise coincided with multiple posts by Musk on X, where he referred to OpenAI CEO Sam Altman as "Scam Altman," accusing him of misappropriating charitable project成果 for personal gain. ChainCatcher highlights the extreme volatility of meme coins like SCAM, which are primarily driven by market sentiment and speculative hype, lacking intrinsic value or practical use. Investors are advised to exercise caution and remain aware of the associated risks.
