Bitcoin mining difficulty falls as miner stress grows
Bitcoin’s latest mining difficulty adjustment delivered a sharp 10.09% cut, marking one of the largest single downward moves recorded in the network’s history.
Data monitored by Galaxy Research showed that the adjustment took place at block height 953,568, reducing mining difficulty from 138.96T to 124.93T.
The drop ranked as the 11th biggest single decline in Bitcoin’s history and the second-largest difficulty reduction recorded so far in 2026.
The adjustment period stretched across 15.6 days, running longer than Bitcoin’s usual two-week target for recalibrating mining difficulty.
Bitcoin’s protocol automatically changes mining difficulty to help keep block production close to its intended schedule, even when mining power rises or falls.
The latest reduction followed a difficult month for miners, as Bitcoin’s price fell by around 15% in June and placed pressure on operating margins.
Lower Bitcoin prices can make mining less profitable, especially for operators facing high electricity costs, debt payments, older machines, or tighter cash flow.
Galaxy Research indicated that some mining operations appeared to shut down or scale back activity during the downturn, lowering the network’s overall hash rate.
A weaker hash rate means less computing power is competing to mine blocks, which can slow the network until the next difficulty adjustment takes effect.
The latest reset helped bring the network back towards balance by making it easier for active miners to find blocks after weaker operators left the market.
The move also highlighted how Bitcoin’s mining system reacts during price stress, as falling prices can force miners offline before the network adjusts to new conditions.
Galaxy Research said the development reflected Bitcoin’s usual pressure cycle during market weakness, where price declines reduce miner participation before difficulty falls to support profitability and security.
The adjustment may offer some short-term relief to miners that remain online, as lower difficulty can improve their chances of earning block rewards.
However, miner conditions still depend heavily on Bitcoin’s price, energy costs, transaction fees, equipment efficiency, and broader market sentiment.
At the time of reporting, Bitcoin price was $64,495.55.
