Bitcoin mining difficulty drops by 5%: What are miners going through behind the 7.9% decline in hashrate?

On July 11, 2026 at 4:09:11 PM, the Bitcoin network completed a new mining difficulty adjustment at block height 957,600. Mining difficulty decreased from 133.87 T to 127.17 T, a drop of about 5%, reducing by about 6.70 T. This was the 14th difficulty adjustment of 2026 and the 8th negative adjustment within the year.

The direct driver of this adjustment is the rapid contraction of hash rate. On July 1, the network hash rate was close to 986 EH/s, but by July 11 it had fallen to about 908 EH/s; within ten days, it dropped by about 7.9%. The previous difficulty cycle (epoch) ran for about 14 days, 18 hours, 9 minutes, which was about 18 hours longer than the 14-day target set by the protocol’s 2,016-block schedule. Converted, the average block time was 10 minutes and 32 seconds—about 5.1% slower than the 10-minute target. A 5% difficulty reduction is precisely the network’s automatic correction to bring block production speed back into the target range.

As of July 11, the difficulty value of 127.17 T is the third-lowest point so far in 2026, only higher than 124.93 T on June 13 and 125.86 T on February 7.

Why hash rate evaporated by nearly 80 EH/s in ten days

Hash rate fell from 986 EH/s to 908 EH/s, evaporating about 78 EH/s in ten days—this figure is several times greater than the entire Bitcoin network’s hash rate in 2020 for a full year. Such rapid and large-scale hash rate exits point to the same fundamental reason: mining economics have worsened.

Since 2026, the Bitcoin price has been under sustained pressure. In the first half of the year, Bitcoin fell by about 33%, dropping from nearly $87,500 to below $59,000 by the end of June. JPMorgan estimates Bitcoin’s production cost is about $78,000, while the price has remained below that level for 5 straight months; currently, about 20% of miners are operating at a loss. Other analysis suggests the network’s estimated production cost range is about $84,000 to $87,000.

When the coin price stays below production cost, lower-efficiency mining rigs that keep running essentially mean losses. This portion of hash rate is forced offline and exits the network, directly reflected in the network’s rapid hash rate decline. This round of hash rate drop from early July to July 11 is, in essence, a “passive capacity reduction” triggered by the inversion between price and cost.

After the difficulty drop, has miners’ revenue improved?

The direct beneficiaries of the difficulty reduction are the miners still operating. With hash rate unchanged, the probability of finding new blocks per unit of hash rate increases, and expected revenue rises accordingly.

Hashprice (expected daily revenue per PH/s per second for miners) closed at about $31.1 on July 11, rebounding about 12.5% from roughly $27.6 around July 1. This means that even if the Bitcoin price does not show a significant rise, the difficulty reduction itself has already provided miners with a certain degree of revenue repair.

However, when you extend the time horizon, this “repair” remains limited. Hashprice has fallen by about 16.4% since January 1, and it is about 37.2% lower than the annual peak of $49.4 in late October 2025. The 2026 Hashprice low point occurred in early June at $27.2.

Miners’ overall revenue situation is also far from optimistic. The 7-day moving-average daily revenue has dropped to about $30 million, clearly below the level in the summer of 2025, which was above $50 million. Transaction fees have fallen below $2.5 million per day, making block subsidies the main source of miners’ income. The highly singular revenue structure significantly increases miners’ sensitivity to Bitcoin price and difficulty adjustments.

What 2026’s difficulty fluctuation pattern reveals

So far in 2026, among the 14 difficulty adjustments, 8 are negative and 6 are positive. Calculated compounded from the time the first adjustment took effect before the first adjustment on January 8, the network difficulty has cumulatively fallen by about 14.22%.

The average adjustment magnitude is only -0.87%, but the average absolute change reaches 5.30%. The large gap between these two numbers reveals a key feature: 2026 difficulty adjustments are not mild fluctuations, but frequent sharp swings. The difficulty was reduced by 10.09% on June 13, then increased by 7.15% again on June 26—completing a violent swing of more than 17 percentage points within two weeks.

This high-frequency, large-magnitude adjustment pattern reflects highly unstable hash rate supply. Miner groups are undergoing a fierce process of survival of the fittest: rigs with low efficiency and high costs are forced to leave, while hash rate with high efficiency and low costs competes for market share. Every large downward adjustment is a signal that a batch of miners is being eliminated; every large upward adjustment results from survivors expanding capacity or new entrants filling the gaps.

What structural changes miners are undergoing

A drop in hash rate and a difficulty reduction are only surface-level signs; deeper changes are happening in the mining industry.

First, miners are shifting from “coin holders” to “sellers.” In Q1 2026, listed mining companies sold a combined total of more than 32,000 BTC; their quarterly sell volume exceeded the total for all of 2025, and even surpassed the roughly 20,000 BTC sell volume during the Terra-Luna collapse in 2022. When mining revenue can’t cover operating costs, miners are forced to sell inventory Bitcoin to keep operating—this behavior is in sharp contrast to the earlier “hold coins and wait for a rise” pattern.

Second, hash rate is shifting from Bitcoin mining to the AI sector. Some mining companies are redirecting hash rate toward AI and high-performance computing for a very straightforward reason: the profitability difficulty of Bitcoin mining has increased significantly. The data center industry expects to invest $75 billion in capital expenditures in 2026, and more than 23 GW of dedicated AI compute capacity is already under construction. For miners with power infrastructure and hash rate operations capability, transitioning to AI hosting or high-performance computing has become a realistic way out.

Third, industry consolidation is accelerating. Smaller players or those with lower efficiency can’t compete with capital-rich, large-scale enterprises. The halving event further compresses block subsidy returns; every time difficulty experiences large volatility, it accelerates this consolidation. Miners that can survive either have extremely low power costs, have the latest generation of efficient mining rigs, or have already completed a shift to diversified business lines.

How the Bitcoin network’s adaptive mechanism runs under pressure

Bitcoin’s difficulty adjustment mechanism is one of the most elegant designs at the protocol layer. Difficulty is adjusted once every 2,016 blocks (about two weeks), with the goal of keeping the average block time around 10 minutes. When hash rate drops and block production slows, difficulty is reduced; when hash rate rises and block production speeds up, difficulty is increased.

This is a pure negative-feedback system that requires no human intervention. The 5% difficulty reduction on July 11 is exactly the mechanism’s automatic response under miners’ economic stress. Difficulty is a lagging indicator—it does not directly track instantaneous hash rate changes, but instead reacts to the mining speed over the previous 2,016 blocks. When hash rate falls, blocks become slower and difficulty is reduced in the next adjustment; the lower difficulty then increases expected revenue per unit of hash rate that remains running.

From June to July, the mechanism went through a complete series of validations: Hashprice bottomed out at about $27.2 in early June; difficulty fell by 10.09% on June 13; then hash rate recovered and difficulty rose by 7.15% on June 26; when hash rate weakened again, difficulty fell again by 5% on July 11. Each adjustment is a “rebalancing” at the network layer, ensuring the system remains stable even under external shocks.

What determines the next direction for hash rate and difficulty

With 908 EH/s in seven-day average hash rate, it is only 3.3% above the low point of 879 EH/s in early February 2026. Hash rate is testing a critical support range.

The future direction of hash rate and difficulty depends on the interaction of three variables:

Bitcoin price. Price is the most core variable determining miner profitability. If the price stays below production costs, more hash rate will be forced to exit, pushing difficulty further down. Conversely, if the price recovers above the cost line, hash rate may flow back into the network.

Energy costs. Bitcoin mining is essentially an energy arbitrage business—miners convert electricity into block rewards. Changes in energy costs directly affect miners’ break-even point. In July, power costs in parts of the U.S. surged significantly due to hot weather, further squeezing miners’ profit space.

Speed of industry transformation. The speed at which hash rate moves from Bitcoin mining to the AI sector will affect the network’s hash rate supply elasticity. If this trend accelerates, hash rate may face sustained structural outflow pressure.

Current hash rate is seeking support in the 880 to 910 EH/s range. Whether this support can hold will determine the direction and magnitude of the next difficulty adjustment. If hash rate continues to fall, difficulty may face further reductions; if hash rate stabilizes or even rebounds in this range, difficulty may turn to an increase in the next adjustment.

Summary

On July 11, 2026, Bitcoin mining difficulty decreased by 5% to 127.17 T, an automatic response by the network to a 7.9% hash rate decline from July 1 to July 11. Within ten days, about 78 EH/s worth of hash rate exited, rooted in the fact that coin price has continued to stay below production costs—about 20% of miners are operating at a loss. After the difficulty drop, Hashprice rebounded 12.5% to $31.1, giving miners still running a certain breathing space; but year over year it is still down 37.2%, and overall revenue pressure has not fundamentally been relieved.

Among the 14 difficulty adjustments since 2026, 8 are negative, with a cumulative decline of 14.22%; the adjustment pattern shows high-frequency, large-variation characteristics. Miners as a group are shifting their roles from “coin holders” to “sellers,” while also facing structural pressures including hash rate drifting toward the AI sector and accelerated industry consolidation. The Bitcoin network’s adaptive mechanism continues to operate under stress; each difficulty adjustment is a system-level rebalancing. Whether hash rate can stabilize in the 880 to 910 EH/s range will determine the direction of the next phase of difficulty adjustment—which ultimately depends on the dynamic interplay between Bitcoin price, energy costs, and the pace of industry transformation.

FAQ

Q1: What does a 5% difficulty drop in Bitcoin mining mean for miners?

A difficulty drop means that with hash rate unchanged, the probability for miners to find new blocks increases, and expected revenue per unit of hash rate improves. On July 11, Hashprice rebounded from around $27.6 at the beginning of the month to $31.1, a gain of about 12.5%. But this is only a relative improvement—Hashprice is still down 37.2% year over year, and miners’ overall revenue pressure has not been fundamentally eased.

Q2: Why did hash rate fall by 7.9% in ten days?

The core reason is that the Bitcoin price has stayed below the mining production cost. JPMorgan estimates production costs at about $78,000, while the Bitcoin price has remained below that level for 5 straight months, putting about 20% of miners in a loss-making state. Loss-making rigs are forced to shut down and exit the network, directly reflected in the rapid hash rate drop.

Q3: What are the characteristics of 2026’s difficulty adjustments?

So far in 2026, out of 14 difficulty adjustments, 8 are negative and 6 are positive; cumulative decline is about 14.22%. The average adjustment magnitude is only -0.87%, but the average absolute change reaches 5.30%, showing a pattern of high-frequency large fluctuations. After the 10.09% reduction on June 13, it increased again by 7.15% just two weeks later, with a notably large swing.

Q4: What structural changes are happening in the miner industry?

Three major changes: first, miners are shifting from “coin holders” to “sellers,” with listed mining companies selling more than 32,000 BTC in Q1 2026; second, hash rate is moving from Bitcoin mining to the AI sector; third, industry consolidation is accelerating, with miners that are less efficient and have higher costs exiting faster.

Q5: How will the next difficulty adjustment go?

It depends on the subsequent trajectory of hash rate. Current hash rate of 908 EH/s is only 3.3% higher than the low point of 879 EH/s in 2026. If hash rate stabilizes in the 880 to 910 EH/s range, difficulty may trend toward stability or turn into an increase; if hash rate continues to fall, difficulty will face further reductions. Ultimately, the outcome depends on the dynamic interplay between Bitcoin price, energy costs, and the pace of industry transformation.
