币界网报道：Hosico Cat (HOSICO), a Solana-based meme coin, surged 44% following the announcement of a giveaway campaign aimed at boosting community engagement. The project plans to distribute tokens to active participants, sparking speculative interest in the asset. Meanwhile, Everscale (EVER) jumped 42% after revealing key upgrades and partnerships during its "6 Conference," where developers highlighted scalability improvements and cross-chain interoperability features. Shentu (CTK) also gained 42.4% amid increased speculative flows, as traders anticipate potential ecosystem expansions. Analysts attribute the price movements to a combination of strategic marketing efforts and broader market optimism around niche altcoins. The Solana ecosystem continues to attract attention with high-velocity meme coins, while layer-1 projects like Everscale focus on technical advancements to compete in the smart contract platform space. Market observers note that these double-digit gains reflect both coordinated community initiatives and opportunistic trading in low-cap assets, though volatility remains elevated across smaller tokens. The developments underscore how targeted campaigns and protocol upgrades can drive short-term price action in the current market cycle.
