Bitcoin mining difficulty has remained below its all-time high of 155.97T for 374 consecutive days, the longest such period in the network’s history. The record was set at block 921,312 on Oct. 29, 2025, while the current stretch has surpassed the 364-day gap following the 2011 crash and the 253-day recovery after China’s 2021 mining ban. Difficulty fell to 124.93T in mid-June 2026, about 20% below the peak, before recovering to 148.36T in October. Mempool.space projects another decline of about 3.7% around Nov. 13, potentially delaying a new record. Bitcoin’s seven-day hashrate has returned to 1 ZH/s, while weak prices, rising costs, bitcoin sales and miners’ pursuit of AI data-center opportunities continue to pressure the sector. Democrats are also seeking limits on data centers that could affect miners competing for power.
