Bitcoin mining difficulty fell 10.09%, marking the second-largest decline of 2026 as lower prices and reduced hashrate pressured miner profitability.
Bitcoin (BTC) recorded its second-largest #mining difficulty drop of 2026 on June 14, falling 10.09% at block 953,568. Galaxy Research confirmed the decline, noting difficulty moved from 138.96 trillion to 124.93 trillion. The adjustment ranks as the 11th-largest downward move in Bitcoin's history.
The drop places current difficulty 20% below its November 2025 peak. The adjustment epoch ran 15.6 days, above the standard 14-day window, as computing power left the network. $BTC has also lost roughly 15% of its value so far in June, which Galaxy Research said has compressed miner margins.
What Drives Bitcoin's Mining Difficulty
Mining #difficulty adjusts automatically to keep block production on a consistent schedule. When hashrate drops, the network lowers difficulty so blocks can still be found at a regular pace. Less computing power on the network means less competition among active miners.
Total hashrate currently stands at 886 exahashes per second (EH/s), according to Blockchain(dot)com. It has dropped 12% in June alone and sits 23% below its October 2025 peak. The February 2026 drop of more than 11% was driven by storm curtailments and a 25% BTC price crash, while the largest drop on record came in July 2021 after China banned Bitcoin mining.
Miners still operating are now earning approximately 9% more per machine, according to crypto trader Merlijn Enkelaar. Hashprice, which measures expected revenue per unit of #hashrate, climbed 13% following the adjustment and currently sits at $33 per petahash per second per day, per Hashrate Index.
Hashprice Returns to $33 Breakeven Zone
The $33 level matters because it brings more miners to a gross breakeven point, The Energy Mag reported on June 13. Efficient, lower-cost mining fleets will remain profitable at this hashprice level. Older machines with higher electricity costs are more likely to be switched off entirely.
The next #difficulty adjustment is scheduled for June 27. Coinwarz projects a 1.69% increase, which would bring difficulty back up to approximately 127 trillion.
