Bitcoin’s network mining difficulty has just recorded its second-largest drop of the year, falling by 10.09% in the latest adjustment. According to Galaxy Research data, the change occurred at block number 953,568, dropping difficulty from 138.96 trillion to 124.93 trillion. This development has sparked renewed debate about the health of the network and miners’ profitability.
What is behind the hash rate plunge?
Galaxy Research points to a sharp decline in the network’s hash rate as the primary driver behind the adjustment. The weakness in Bitcoin’s price at the start of June saw a roughly 15% drop, heavily squeezing the profit margins of miners, especially those with higher operational costs. Many operators responded by shutting down older mining devices to cut losses.
According to Galaxy Research, the approximately 15% price slump in June put significant pressure on miners’ margins, prompting some hash power to go offline as a result.
In addition to rising costs, another trend is shaping the industry: Electric power is increasingly being diverted from Bitcoin mining to high-performance computing and artificial intelligence data centers. This shift, especially among large-scale facilities, is altering how organizations allocate their energy resources.
Mini Glossary: The hash rate reflects the total computational power contributed by all miners securing the Bitcoin network. High-performance computing refers to infrastructure used in tasks such as scientific modeling, big data analysis, and artificial intelligence training.
Network speed falls behind target as block intervals lengthen
The decline in mining power has had an immediate impact on how fast the Bitcoin network operates. Due to the recent drop, the previous difficulty period lasted 15.6 days, exceeding Bitcoin’s standard target of a 14-day interval between adjustments. Bitcoin’s difficulty adjusts every 2,016 blocks to keep block times on track.
Currently, the average block time stands at 13.23 minutes, a figure about 3.23 minutes slower than the expected average. Analysts highlight that these numbers are calculated using daily difficulty averages and via the network’s SHA 256 algorithm.
Short term relief ahead for miners?
Over the last 90 days, the average change has been minus 13.86%. Despite this, experts believe the most recent 10.09% adjustment could offer some short-term relief for active miners. Industry source EnergyMag forecasts that this cut could lift BTC production per active hash rate by more than 9%.
Analysts also note that this adjustment could push the hash price—the expected daily revenue per unit of compute power—back above the $30 threshold per PH/s, a key benchmark for mining profitability.
The next difficulty adjustment is expected on Thursday. Current projections point to an additional possible decline of 24.43%. Should this scenario materialize, the mining difficulty could fall from 124.93 trillion to 94.41 trillion, providing further relief to miners navigating rising costs.
