Bitcoin miners are facing increased pressure following a 6.31% rise in mining difficulty, reaching 155.97 trillion, marking the third-largest increase of 2025. Despite this, the network's hashrate remains robust, exceeding 1,100 exahash per second (EH/s). October's mining revenue totaled $1.595 billion, showing a slight improvement from September. However, the hashprice has decreased from $50.66 to $44.67 per petahash per second (PH/s) over the past month. With Bitcoin's price declining and onchain fees remaining low, miners are challenged by unfavorable conditions in two of the three key profitability factors: difficulty and price.
