Key Highlights
Mining difficulty decreased 10.09%, falling from 138.96 trillion to 124.93 trillion
Marks the 11th-largest difficulty reduction in Bitcoin’s entire history
BTC price declined approximately 15% throughout June, compressing miner profitability
Hashprice recovered to above $30 per petahash per second daily after the adjustment
Average Bitcoin production costs are estimated at $84,300, significantly exceeding the current ~$63,780 trading price
The Bitcoin network experienced a significant 10.09% mining difficulty reduction on Sunday, with the metric declining from 138.96 trillion to 124.93 trillion at block height 953,568. According to Galaxy Research, this represents the 11th-largest downward difficulty adjustment ever recorded on the network.
This marks 2026’s second-most significant difficulty decrease, trailing only February’s 11.16% reduction. The adjusted difficulty level represents the lowest reading observed since July 2025.
Factors Behind the Difficulty Decrease
Bitcoin’s market price has declined approximately 15% during June, bringing the asset to around $63,780. This price deterioration compressed profit margins for mining operations, compelling certain operators to deactivate equipment that became unprofitable.
With machines shutting down, block production slowed noticeably. The preceding epoch extended to 15.6 days, exceeding the standard 14-day benchmark. This extended block time initiated the automatic downward difficulty recalibration.
Bitcoin’s difficulty mechanism adjusts every 2,016 blocks to maintain approximately 10-minute block intervals. When network hashrate decreases, difficulty adjusts downward accordingly.
Current network hashrate stands between 886 and 894 exahashes per second. This represents a 12% monthly decline and sits 23% below the October peak, based on Blockchain.com data.
The reduction benefits surviving miners through decreased competition. Active mining equipment now generates approximately 9% to 11% more Bitcoin per hashrate unit.
Hashprice Recovers Past $30 Threshold
Hashprice, which measures miner revenue per hashrate unit, increased 13% following the adjustment. Current levels range around $32 to $33 per petahash per second per day, according to Hashrate Index data.
This threshold is significant as it brings more operations closer to gross profitability. Modern, efficient equipment will maintain profitable operations, while older, energy-intensive hardware faces shutdown.
This represents 2026’s third downward adjustment exceeding 5%. February’s reduction resulted from winter storm disruptions. The June decline stems from both price weakness and structural changes, as certain miners reallocate computational resources toward artificial intelligence and high-performance computing applications.
Bitcoin’s estimated comprehensive production cost averages approximately $84,300, based on Checkonchain’s difficulty-regression analysis. With Bitcoin trading near $63,780, most mining enterprises operate below full-cost profitability.
Network conditions have begun stabilizing. Average block production times have returned to near 10-minute intervals. The subsequent difficulty adjustment is anticipated around June 27, with projections indicating a modest 1.69% increase, suggesting hashrate stabilization.
Future difficulty trajectories depend substantially on Bitcoin’s price movement. A price recovery could reactivate dormant equipment. Sustained weakness, or continued miner transitions to AI computing, may permanently sideline that capacity.
