币界网报道：Pi Network's native token Pi surged 19% ahead of its annual Pi2Day celebration on June 28, as the project continues transitioning toward open mainnet launch. The mobile-mined cryptocurrency, which boasts over 55 million engaged users worldwide, saw its price jump from $22.50 to $26.80 within 24 hours according to exchange data. Core Team members confirmed the network has processed over 15 million KYC verifications and migrated 4.8 million wallets to the enclosed mainnet during its current third phase. While still not tradeable on major exchanges, Pi's value is determined through peer-to-peer transactions on community platforms. The upcoming Pi2Day event is expected to feature updates on the project's roadmap, including potential timelines for open mainnet transition and new utility applications for the token. Developers recently launched Pi Ad Network and Pi Browser to expand ecosystem functionality ahead of full decentralization.
