Bitcoin’s network difficulty eased noticeably on Sunday, falling by 10.09% in what Galaxy Research described as the blockchain’s 11th-largest downward adjustment. The change reduces the work required to find new blocks, offering a short-term relief for miners coping with weaker margins amid a softer Bitcoin price.
According to Galaxy Research, difficulty moved from 138.96 trillion to 124.93 trillion at block 953,568. The adjustment came after an “epoch” lasting 15.6 days—longer than the usual 14—suggesting a meaningful amount of mining capacity went offline during the period.
Key takeaways
- Bitcoin mining difficulty dropped 10.09% to 124.93 trillion, easing block-finding conditions for miners.
- Galaxy Research linked the adjustment to a longer-than-usual epoch (15.6 days) and offline hashrate.
- Total hash rate is about 886 EH/s, down 12% this month and 23% from its October peak, per Blockchain.com.
- Hashprice rose to around $33 per PH/s per day, potentially pushing more fleets toward gross breakeven, according to Hashrate Index and The Energy Mag.
- Next difficulty adjustment is expected on June 27, with Coinwarz forecasting a slight increase to roughly 127 trillion.
Why difficulty fell: margins pressured, hashrate thinned
Mining difficulty adjusts to help keep Bitcoin’s block production rate stable even as the total amount of mining power changes. When less hashrate participates, difficulty can decrease so blocks remain discoverable at the target pace.
Galaxy Research said Bitcoin is down roughly 15% so far in June, a move it framed as having “squeezed miner margins.” In that environment, some miners—particularly those with higher operating costs—may turn down or disconnect equipment, reducing competition and lowering the network’s effective hashrate during the adjustment window.
Galaxy Research also pointed to the timing of the last adjustment cycle: the epoch ran 15.6 days rather than 14, consistent with hashrate coming offline earlier or more persistently than normal. The outcome was the second biggest difficulty decline of 2026, and about a 20% drop from the difficulty peak recorded in November.
Hash rate declines and the miner “breathing room” effect
While difficulty determines how hard it is to mine blocks, total hash rate reflects how much computing power is actively competing. Blockchain.com data cited in the report places total hash rate at approximately 886 exahashes per second (EH/s). That figure is down 12% since the beginning of the month and about 23% below the network’s October peak.
With less hashing competing, miners that remain online typically see an improvement in expected rewards per machine—because each miner’s share of the network’s work rises when the overall hashrate falls. Crypto trader Merlijn Enkelaar said the remaining miners are earning around 9% more per machine.
For investors and operators, this combination matters: difficulty reductions can offset part of the revenue hit from falling coin prices, helping keep marginal miners from exiting as quickly. That does not guarantee profitability for every operator—electricity costs, fleet efficiency, and hedging strategies still determine who stays competitive—but it can shift which mining capacity is economically viable.
How far the relief goes: hashprice rises above a key threshold
Alongside the difficulty move, the metric used to gauge operational economics—hashprice—improved. Hashrate Index data cited in the report shows hashprice climbing 13% to about $33 per petahash per second per day.
Hashprice is often used as a practical proxy for how much revenue miners may earn per unit of hash power, before considering all costs. The Energy Mag reported that $33 represents an important threshold because it can move more efficient mining fleets toward a gross breakeven point.
The same report noted an expected divergence in outcomes: efficient operators may continue generating profits even at lower hashprice levels, while older-generation machines with higher electricity costs are more likely to be idled. In other words, the difficulty drop may reduce pressure overall, but it can also accelerate the ongoing shakeout between newer, lower-cost hardware and higher-cost legacy equipment.
Looking ahead to June 27: a rebound or renewed pressure?
Bitcoin’s next difficulty adjustment is expected on June 27. Coinwarz predicts a slight increase of about 1.69% to around 127 trillion.
What happens after this point will depend on whether the reduced hashrate is a temporary pause or the start of a longer re-pricing of mining economics. If a portion of offline capacity returns—raising hash rate—the difficulty is more likely to creep upward again at the next adjustment. If equipment remains curtailed as Bitcoin’s price stays under pressure, the downward pressure on difficulty may persist.
For now, Sunday’s decline provides a measurable reprieve: fewer competitive hashes to mine against and a higher hashprice than before the adjustment. Readers should watch the next few weeks for changes in reported network hashrate, as that will largely determine whether June 27 brings relief or the return of tougher mining conditions.
