Zero-Knowledge Proof (ZKP), Ethena (ENA), Cronos (CRO), and Pi Network (PI) have been identified as leading pre-sale cryptocurrency projects for 2025, according to Biji Network. ZKP is noted for its robust infrastructure and consistent daily token auctions, positioning it as a strong contender in the market. Ethena, despite its potential, faces challenges with liquidity and price volatility, while Cronos maintains stability but lacks recent growth momentum. Pi Network is dealing with issues related to upcoming token unlocks and limited liquidity on exchanges. The report underscores the importance of tangible progress and transparency for these projects to succeed in 2025.
