币界网报道：Pi Network's native token PI surged over 20% on Pi2Day (June 28) amid growing anticipation for its potential open mainnet launch in 2025, though uncertainty remains about the project's timeline. The token, currently trading around $40 on some exchanges despite not being officially listed, saw its price spike as the Pi community celebrated its annual event. While developers claim over 55 million engaged users are mining PI tokens through mobile apps, critics question the network's decentralization and actual adoption. The project's white paper outlines plans for a three-phase rollout, with the final "Open Network" phase expected to enable full decentralization and external exchange listings. However, with no confirmed mainnet date and limited real-world utility demonstrated so far, analysts caution investors about the speculative nature of PI's current valuation.
