Bitcoin Mining Difficulty Sees Historic First-Ever Annual Decline

Bitcoin mining difficulty is on track for its first-ever annual decline, according to data shared by well-known quantitative analyst PlanB. The metric has fallen to approximately 126.2 trillion (T) in 2026, down from 148.3T at the end of 2025.

This marks a significant departure from historical norms, where mining difficulty has consistently increased year-over-year since the network's inception in 2009.

The decline is likely driven by economic pressures on miners, who may be shutting down unprofitable operations due to factors such as lower Bitcoin prices or rising energy costs.
