Five altcoins, including Jupiter (JUP) and Ethena (ENA), have surged over 60% this week, highlighting concentrated momentum in the altcoin market. These tokens demonstrated sustained volume and structured trading activity, with performance synchronized across both DeFi and meme-based tokens. The price increases occurred during a period of broad altcoin participation, yet remained focused on a select group of assets. Jupiter recorded a remarkable weekly advance, aligning with elevated trading volume across major exchanges, reflecting sustained demand. Ethena followed closely, showing a steady rise indicative of controlled accumulation. TROLL, Mogcoin (MOG), and Gigachad (GIGA) also joined the top-tier gainers, each displaying unique trading patterns and volatility, contributing to their status as leading short-term performers in the altcoin market.
