Robinhood Chain meme coins posted broad gains across Aug. 10-12, according to GMGN market data cited by BlockBeats. On Aug. 10, CASHCAT, which had recently faced questions over alleged insider positioning ahead of a listing, stabilized after an earlier decline; its weekend gain briefly reached 30%, and it rose nearly 10% over 24 hours, taking its market capitalization to $145 million with $27.9 million in trading volume. STONKBROKER climbed more than 16% to an $80 million market capitalization with $4.8 million in 24-hour turnover, while MANCER, a StonkBroker ecosystem project, gained more than 14% to reach a $10.24 million market capitalization. By Aug. 12, HMM, also known as Thinking Cat, had become the standout mover, rising about 167% over 24 hours, pushing its market capitalization to an all-time high of about $20.68 million before easing to around $19.11 million, with roughly $2.3 million in trading volume. BlockBeats said HMM's momentum was tied to its use as a public demonstration meme coin for Wirebot, attention around the PONS narrative and Robinhood Chain, and an alpha listing on a trading platform, while warning that meme coin trading is highly volatile and often driven by sentiment and thematic speculation rather than practical use cases.
