Pi Network's token price climbed back above $0.15 following a significant mainnet upgrade to Stellar protocol version 23. The upgrade, which included migrating the operating system to Ubuntu 24 and updating the database engine to PostgreSQL 16, aims to enhance network performance, security, and scalability. Despite these improvements, PI remains under pressure from recent losses, trading at approximately $0.1518. Technical indicators suggest potential for a short-term rebound. The 4-hour RSI indicates oversold conditions, while the MACD shows fading bearish momentum. However, PI is still below key moving averages, with resistance at $0.1519. A break above this level could lead to further gains, while a drop below $0.1463 might trigger additional declines.
