币界网报道：Pi Network's native token PI surged 38% ahead of its annual Pi2Day celebration on June 28, reaching $41.50 before settling around $39. The rally comes as the project prepares for its anticipated open mainnet launch, though no specific date has been announced. Currently trading on multiple exchanges including HTX and BitMart, PI remains unavailable on top-tier platforms like Binance and Coinbase. The project's core team recently completed its third "hackathon" to boost ecosystem development, while community members organized over 100 offline events globally for Pi2Day. Despite its growing popularity with over 55 million engaged users, Pi Network continues operating in enclosed mainnet mode, requiring KYC verification for wallet access. The project maintains its unique mobile mining approach, allowing users to earn PI through daily check-ins without energy-intensive mining hardware.
