Bitcoin mining difficulty shrinks 14% from this year's high as plunging revenues force operators to pivot

Difficulty falls as weak mining economics reduce capacity, while forward markets signal little relief through year-end.

The top 3

  1. Top 3 Largest Percentage Difficulty Drops: The largest Bitcoin mining difficulty drop was approximately 28% in July 2021 following China's mining ban, with a significant drop also occurring during the 2018 bear market, and a recent 19.9% decline from November 2025 to July 2026 ranking as the third deepest since ASICs became standard.
  2. Bitcoin Network's All-Time Difficulty Peaks: Bitcoin's mining difficulty has repeatedly reached new all-time highs, with a record of approximately 92.67 trillion on September 10, 2024, and further climbing to 134.7 trillion by September 2025, reflecting continuous growth in network hashrate.
  3. Longest Sustained Periods of Difficulty Decline: The current Bitcoin mining difficulty decline, extending approximately 287 days, represents one of the longest sustained contractions in Bitcoin's history, comparable to the period following China's 2021 mining ban.
