A significant technical upgrade was introduced for Pi Network at the beginning of last month. Around the March 1 deadline for mainnet nodes, there was considerable volatility observed in the PI coin price. Currently, the price remains stable around $0.17, indicating a modest 0.50% increase over 24 hours.

I believe this upgrade event was quite important because all node operators were required to update on time. Nodes that did not update would disconnect from the network. This was to strengthen Pi Network's decentralized consensus mechanism, as nodes are responsible for transaction validation and maintaining network stability through the Stellar Consensus Protocol.

Regarding technical charts, the RSI is around 53, which means PI is currently in a neutral zone. The MACD shows signs of a bullish crossover, which could indicate continued buying momentum. Immediate resistance is around $0.18. If the Pi Network coin price breaks above this level, it could reach $0.20, which was the high earlier this month.

As for support levels, $0.16 remains a strong base where buyers are repeatedly attracted. If this level breaks, the next support is near $0.14. The market sentiment is generally positive, but volatility can return at any time. Considering the momentum of the Pi Network price, an interesting move could happen in the next few weeks.
