What Happens After The Protocol 21 Upgrade

• PI trades at $0.1718, up 1.54%, pressing into the lower Bollinger Band at $0.1636 with the SAR at $0.2026 overhead.
• Protocol 21 hard fork deadline is today, April 6, with non-compliant nodes facing immediate disconnection from Mainnet.
• Pi Network has crossed 526 million KYC checks and 18 million verified users through its decentralized validator network.

Pi Network’s mandatory Protocol 21 upgrade deadline arrives today. Every Mainnet node must complete the hard fork by April 6 or face immediate disconnection and exclusion from consensus. Meanwhile, PI trades at $0.1718, recovering slightly from last week’s sell-off that followed the buy-the-rumor-sell-the-news pattern that played out around Pi Day and the Kraken listing in March.

PI Daily Chart: Lower Bollinger Band Holds As Bands Begin To Compress

The daily chart shows PI coming off the March spike high near $0.3050, which was driven by Pi Day anticipation and the Kraken listing. Once both events passed, the classic sell-the-news pullback arrived, pushing price back toward the lower Bollinger Band at $0.1636. That band flattened the February low near $0.1380, and price is now sitting just above it at $0.1718.

The Bollinger Bands are beginning to compress after the post-spike contraction. The upper band sits at $0.1796, the middle band at $0.1957, and the lower band at $0.1636. Price is between the lower and upper bands, closer to the lower end, with the SAR at $0.2026 overhead and bearish. The ascending dotted trendline from the February low is rising toward current price, adding support from below.

A daily close above the middle band at $0.1957 would be the first meaningful recovery signal since the March peak. Losing the lower band at $0.1636 on a daily close puts the February low at $0.1380 back in view.

Pi Key levels for April 7:

• Lower Bollinger Band: $0.1636
• Upper Bollinger Band: $0.1796
• Middle Bollinger Band: $0.1957
• SAR resistance: $0.2026
• February low: $0.1380
• March high: $0.3050

Why PI Dropped After The Kraken Listing

The March spike to $0.3050 was built on two catalysts: Pi Day announcements and the Kraken listing, which made PI available to millions of US users for the first time. 

Both events delivered, and both triggered selling rather than continuation. Investors accumulated ahead of the events, the events occurred, and the exit began. However, the pullback does not reflect a change in fundamentals. It reflects position unwinding by traders who bought the anticipation. 

Protocol 21: What Today’s Deadline Actually Changes

The Protocol 21 upgrade is described by the Pi OpenMainnet account as a security and compatibility hard fork, not an optional update. All Mainnet node operators must complete the upgrade by today to remain synchronized with the network. Nodes that miss the deadline face immediate disconnection and exclusion from consensus participation.

The forced alignment serves a specific purpose: it eliminates fragmentation in the node network and ensures all active validators are running compatible software. Pi Network has reached 526 million KYC checks and 18 million verified users through its decentralized validator network, numbers that make network cohesion increasingly important as the ecosystem scales. A hard fork that enforces full compliance at this stage is a maturity signal, not a crisis, and the team has framed it explicitly as a step toward a more scalable and lasting network architecture.

PI Price Prediction: What Happens After The Protocol 21 Upgrade

• Upside: Protocol 21 completes cleanly with high node compliance and PI holds the lower Bollinger Band at $0.1636. A daily close above the middle band at $0.1957 signals the sell-the-news correction is over. From there the SAR at $0.2026 is the next test, and clearing it puts $0.2300 to $0.2500 in view as April targets. Continued KYC growth and ecosystem announcements following the upgrade would give retail a reason to re-enter.
• Downside: Lose the lower Bollinger Band at $0.1636 on a daily close and the ascending trendline from February breaks simultaneously. The February low at $0.1380 becomes the next floor, and without a fresh catalyst to replace the Pi Day and Kraken listing narratives, a retest of $0.1380 with the Bollinger Bands still wide could happen quickly.
