Bitcoin mining difficulty fell by 10.09% on June 14, 2026. This second largest decline of the year offers immediate respite to miners, after a sharp contraction in the hashrate and a further deterioration in their profitability.
In brief
- Bitcoin mining difficulty dropped by 10.09% on June 14.
- Active miners will produce more BTC at equal power.
- The drop in hashrate also reflects the shift in capabilities towards AI.
Bitcoin reacts to falling hashrate
The network difficulty increased from approximately 138.96 trillion to 124.93 trillion. This adjustment comes after a clear drop in the hashrate, or the total computing power mobilized to secure bitcoin and produce its blocks.
At the end of May, the seven-day moving average of the hashrate was still hovering around 1 zettahash per second. It then fell to near 861 exahashes per second around June 10, before partially rising to around 894 EH/s.
This contraction slowed down block production. However, bitcoin aims for an average interval close to ten minutes. Its protocol therefore automatically modifies the difficulty every 2,016 blocks, or approximately every two weeks.
A mechanical respite for miners
Lower difficulty means that machines that are still connected have a greater chance of producing a block. At equal power, active miners can now obtain more bitcoins than before the adjustment.
All things being equal, a drop of 10.09% improves the amount of BTC produced per unit of power by approximately 11%. The relief could, however, remain limited if the price of bitcoin falls again or if transaction fees decrease.
The fall of BTC towards $60,000 at the start of the month had already caused the hashprice to fall below $30 per petahash per second. This indicator measures the daily income generated by computing power. Below this threshold, old machines and expensive installations become particularly vulnerable.
The price of bitcoin does not explain everything
The temporary collapse of the hashrate partly results from the economic difficulties of miners. When revenues no longer cover electricity, maintenance and debt repayment, some operators unplug their least efficient equipment.
Texas could also have amplified the movement. June marks the start of the so-called Four Coincident Peaks season. During this period, large consumers reduce their usage during peaks that may determine their future electricity transmission costs.
Texan miners therefore have an interest in temporarily shutting down their machines during certain summer peaks. As this state concentrates a significant part of North American mining, these interruptions can cause visible variations in the global hashrate.
Artificial intelligence diverts electricity
Another change is looming in the background. Several mining companies are now reallocating part of their infrastructure to high-performance computing and data centers dedicated to artificial intelligence.
This strategy responds to an economic reality. AI-related contracts can produce more predictable revenue than mining, whose profitability depends on bitcoin price, difficulty, network fees, and energy cost.
However, the drop in difficulty does not mean that bitcoin's security is collapsing. Above all, it shows that the protocol adapts when machines leave the network. Remaining operators receive a larger share of the rewards, which may attract new capacity or encourage equipment restarts.
The decline of 10.09% therefore temporarily improves margins, without resolving the structural crisis in the sector. Between bitcoin under pressure, high energy costs and the shift to AI, miners must now choose where their electricity earns the most.
