Bitcoin Difficulty Drops 10% to 11-Month Low

Bitcoin mining difficulty fell 10.09% at block 953568 to 124.93 trillion on June 13, the lowest reading since July 12, 2025, after the network’s computing power dropped to roughly 893 exahashes per second from levels above 1,000 EH/s.

The decline was the second-largest downward adjustment recorded in 2026. Difficulty is recalculated every 2,016 blocks to target an average block time near 10 minutes; the reduction reflects lower sustained hashrate and slower block production in the run-up to the June 13 epoch.

Hashprice, the estimated daily revenue per petahash per second, fell below $28 per PH/s last week and has since recovered to about $32.51 per PH/s based on industry data. The revenue decline contributed to tighter margins for miners and coincided with the drop in effective network computing power.

Difficulty has swung sharply this year. The year’s peak of 146.47 trillion was recorded on Jan. 8, leaving a gap of about 21.54 trillion between that high and the current low. Of the 12 difficulty epochs so far in 2026, seven produced negative adjustments and five produced increases. The largest single reduction this year occurred on Feb. 7, when difficulty fell 11.16%, followed 12 days later by a 14.73% increase on Feb. 19.

Reduced hashrate slowed block production in the weeks before the June 13 recalibration, with average block intervals exceeding 11 minutes for much of that period. After the difficulty fell, block times have moved back toward target levels, averaging about 10 minutes and 37 seconds over the most recent 24-hour window. Nearly 100 blocks have been mined since the adjustment took effect.

The next difficulty recalculation is projected on or around June 28. Whether difficulty moves higher or remains near current levels will depend on hashrate and block production over the coming two weeks. Bitcoin traded in the mid-$64,000s during the same period, with a snapshot price of $64,549 on June 14 at 8 a.m. Eastern time.
