Bitcoin mining difficulty drops by 10.09%, its second largest decline of the year

Bitcoin mining difficulty dropped by 10.09% on June 14, 2026. This second largest decline of the year offers immediate relief to miners after a sharp hashrate contraction and a new degradation of their profitability.

Bitcoin reacts to hashrate drop

The network difficulty fell from about 138.96 trillion to 124.93 trillion. This adjustment comes after a clear hashrate drop, which is 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 around 1 zettahash per second. It then dropped near 861 exahashes per second around June 10, before partially rising back to about 894 EH/s.

This contraction slowed block production. Bitcoin targets an average interval close to ten minutes. Its protocol therefore automatically modifies the difficulty every 2,016 blocks, roughly every two weeks.

A mechanical relief for miners

A lower difficulty means that machines 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 else being equal, a 10.09% drop improves the amount of BTC produced per unit of power by about 11%. However, the relief could remain limited if Bitcoin’s price falls again or if transaction fees decrease.

The BTC drop to around 60,000 dollars earlier this month had already pushed hashprice below 30 dollars per petahash per second. This indicator measures daily revenue generated by computing power. Under this threshold, old machines and costly installations become particularly vulnerable.

Bitcoin price doesn’t explain everything

The temporary hashrate collapse partly results from miners’ economic difficulties. When income no longer covers electricity, maintenance, and debt repayment, some operators disconnect their less efficient equipment.

Texas may also have amplified the movement. June marks the start of the so-called Four Coincident Peaks season. During this period, major consumers reduce their usage during peaks that may determine their future electricity transmission fees.

Texas miners therefore have an interest in temporarily shutting off their machines during certain summer peaks. Since this state concentrates a significant share of North American mining, these interruptions can cause visible fluctuations in global hashrate.

Artificial intelligence diverts electricity

Another change is emerging in the background. Several mining companies now reallocate 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 income than mining, whose profitability depends on Bitcoin price, difficulty, network fees, and energy cost.

However, the difficulty drop does not mean that Bitcoin security collapses. It mainly shows that the protocol adapts when machines leave the network. Remaining operators receive a larger share of rewards, which can attract new capacity or encourage equipment restarts.

The 10.09% decline therefore temporarily improves margins without resolving the sector’s structural crisis. Between a pressured Bitcoin, high energy costs, and the switch to AI, miners must now choose where their electricity yields the most.
