On December 7th, per GMGN market data (link: https://t.me/gmgnaibot?start=i_m4TE56o8), the Solana-based meme coin MOODENG is up over 43% in the past 24 hours, with its current market capitalization at $104 million. ### Notes on U.S. language habits adapted: 1. **Date lead-in**: Added "On" before the date (natural for time-bound news). 2. **Market jargon**: Used "is up" (common for quick price updates) instead of just "surged"; "market capitalization" is formal but acceptable, while "market cap" (shorter) is also widely used in U.S. crypto news (could also use *"with a current market cap of $104 million"*). 3. **Conciseness**: Kept the link clear but unobtrusive (standard for U.S. financial/tech快讯). 4. **Capitalization**: Lowercased "meme coin" (standard unless part of a brand name; MOODENG remains uppercase as the coin’s identifier). This version aligns with U.S. news style—clear, concise, and focused on key metrics (price change, market cap, platform).
