- Bitcoin difficulty records its biggest decline of 2026 amid hashrate.
- Galaxy Research links lower hashrate to miner profitability pressures.
- Another major difficulty reduction could arrive if hashrate weakens.
The Bitcoin hashrate had been declining for past few weeks and has finally stabilised at the highest mining difficulty drop of 2026. Galaxy Research data indicates that Bitcoin’s mining difficulty has decreased by 10.09% to 124.93 trillion from 138.96 trillion in block 953,568. This difficulty adjustment is the second largest down adjustment difficulty this year, and the 11th largest in Bitcoin’s history. Most important, the downward movement suggests that mining activity is continuing to slow and was stunted by activity across the network.
Weaker market conditions were a big factor in the drop in hashrate, according to Galaxy Research. In the early part of June, Bitcoin saw a decline in its value of about 15%, adding more pressure to the profitabilty of mining. Some operators, therefore, lowered their capacity by closing down less efficient and older machines.
At the same time, the competition to use electricity to power the mines is also increasing. More resources to which power providers have turned are AI infrastructure and AI High Performance Computing facilities. Other mines have encountered problems in obtaining the same amount of energy that enabled them to work at the same speed. All this reduced the strength of the Bitcoin network’s protection. The difficulty adjustment mechanism responded to the removal of the hashrate, by lowering the hashrate required to build blocks.

Slower hashrate impacts Bitcoin’s operating pace
Bitcoin’s block production schedule was directly impacted by the drop in mining power. The previous adjustment period of 15.6 days is longer than the target of 14 days set by the network, reports Galaxy Research. Bitcoin’s difficulty is adjusted every 2,016 blocks to keep the rate of block creation constant. The recent participation, however, was not as high as needed, resulting in a significant slowing of the network.
According to the latest data, Bitcoin’s average block time is 13.23 minutes. As a result, the network is running at a speed exceeding more than ten minutes, the target it was designed for. The adjustment period is a longer time frame that offers further proof of the drop in hashrate. The average difficulty was down by -13.86% in the last 90 days, suggesting that mining activity continues to decrease.
Lower difficulty could improve miner economics
When it comes to participation in mining, the drop in hashrate can be worrisome, however, it can be good news for those miners who still still participate as the difficulty will be lowered. The operators are able to earn more profit from the same monetary investment as they have to deal with less competition.
The new tweak might boost the overall output per hashrate of Bitcoin by over 9%, EnergyMag reports. Moreover, mining hash price could reach the above $30/petahash per second mark. The industry is facing difficulties, but the improved economics could make some operators more willing to continue operating their machines. The market situation, and energy expenses, are still significant considerations which will affect future mining.
Now the focus is on the next difficulty adjustment of Bitcoin. With the network hashrate still under pressure, the current estimates are that another significant drop-off is still to be expected. A projected 24.43% reduction would lower mining difficulty to 94.41 trillion from 124.93 trillion, representing another substantial challenge for a network with decreasing participation.
This marks the biggest difficulty drop for Bitcoin for 2026, continuing its trend of difficulty decreases due to profitability issues and changing energy investment priorities. It could, however, be employed to briefly relieve the pain of active miners as well as help network adapt to new conditions.
