Bitcoin’s mining difficulty has fallen roughly 19% from its November 2025 peak to approximately 126.23 trillion as of July 25, 2026, marking the largest decline since China’s 2021 mining ban. This drop is driven by Bitcoin trading consistently below $65,000 combined with the April 2024 halving that halved block rewards from 6.25 BTC to 3.125 BTC. Major public miners including Hut 8, Core Scientific, and TeraWulf sold over 32,000 BTC in Q1 2026 alone to cover operating costs. Facing sustained economic pressure, many operators are pivoting their power contracts and infrastructure toward artificial intelligence and high-performance computing workloads. For the Bitcoin protocol, this difficulty adjustment reflects the system working as designed, maintaining consistent block production even as miners exit the network.
