According to Altcoin Daily, the author posted a 24-hour call on X asking users to like the post and name an undervalued coin, stating the post will be deleted in 24 hours and a participant might receive a surprise DM, creating a time-boxed thread of altcoin tickers to monitor, source: Altcoin Daily on X, Dec 8, 2025. Traders can scan replies within the 24-hour window to identify repeatedly mentioned coins and timestamp engagement spikes since the prompt explicitly requests undervalued coin names, source: Altcoin Daily on X, Dec 8, 2025. Any trade consideration should be limited to coins actually cited in the replies and validated for liquidity and listings, as the only signal provided is user-submitted names prompted by the author, source: Altcoin Daily on X, Dec 8, 2025.
