Firsthand Bitcoin · Data · Bitcoin miners
Estimated change: -6.50%. 536 blocks remaining. 73% of the period done. Expected November 13, 2026. Read November 9, 2026 from the pace of blocks so far in this 2,016-block period.
The last adjustment was +5.54% on October 29, 2026 at block 973,728.
Difficulty retargets every 2,016 blocks so that blocks keep arriving about every ten minutes. If the current period is running ahead of schedule, the network has more hashrate than the difficulty assumes and the next adjustment will be upward by the same proportion; if it is running behind, downward. The estimate is the pace so far, so it firms up as the period goes on. For a miner an upward adjustment is a pay cut of the same size; a downward one is a pay rise.
