The computational challenge required to mine Bitcoin has reached an all-time peak, exceeding 136 trillion. This increase in network difficulty intensifies pressure on Bitcoin miners already grappling with reduced earnings.
The network adjustment, which occurred at block number 913,248, represents a 4% increase from the previous level of 129.6 trillion. Data from Mempool shows this marks the fifth consecutive upward adjustment since June.
Bitcoin Miners Face Tight Margins With Record Difficulty And Weakening Income
This difficulty adjustment is a core feature of Bitcoin’s architecture. The difficulty is automatically recalibrated roughly every two weeks (every 2,016 blocks) to maintain a target block creation time of approximately ten minutes.

An increase in difficulty signals heightened competition as more computing resources are dedicated to mining. Conversely, a decrease suggests miners are leaving the network. In either case, the adjustment mechanism ensures a relatively consistent rate of new block generation.
This rising difficulty arrives at a particularly challenging moment for Bitcoin miners.
According to data from Hashrate Index, the “hashprice” – a measure of miner revenue for a given amount of computing power – has decreased to around $51.
This represents the lowest level observed since June, highlighting growing revenue pressures amidst increasingly fierce competition among miners.
Analysis from Hashrate Index emphasized these economic challenges during August. The average Bitcoin hashprice for the month was $56.44, approximately 5% lower than the average recorded in July.
The firm also observed that transaction fees on the Bitcoin network provided minimal revenue support throughout the month.
Hashrate Index reported that Bitcoin miners earned an average of just 0.025 BTC per block from fees – a 19.6% decrease compared to July. This is the weakest performance observed since late 2011. In US dollar terms, this equates to approximately $2,904 in average daily fee income, representing a nearly 20% month-over-month decline and the lowest level since early 2013.
Therefore, Bitcoin mining operations are currently facing a difficult situation. The combination of record-high mining difficulty and shrinking revenue is squeezing their profit margins.
This signifies that miners may struggle to maintain profitability for the rest of the year, unless either the price of Bitcoin rises significantly or increased on-chain activity leads to higher transaction fees.
