Bitcoin miner profitability has been under significant pressure in recent weeks, driven by a combination of declining hashprices, record-high network hashrates, low transaction fees, and a recent correction in Bitcoin's price. According to a November 4, 2025, analysis, hashprice—a key metric measuring daily revenue per petahash per second (PH/s)—has dropped to a multi-month low of $43.1 PH/s, squeezing miners' margins amid Bitcoin's price dip and subdued network activity. This represents a roughly 20% decline in profitability over the past month, with overall miner revenue per day falling 22% from $59.56 million to $46.37 million as of early November 2025.
Despite these challenges, some large-scale miners have reported strong quarterly results by diversifying operations and leveraging higher average Bitcoin prices year-over-year. For instance, Marathon Digital (MARA) announced a record Q3 2025 revenue of $252 million on November 4, 2025—up 92% from the previous year—swinging from a $124.8 million loss to a $123.1 million net profit. The company attributed this to an 88% rise in Bitcoin's average price, paired with new power deals and AI infrastructure integrations, though mining volume itself didn't drive the bulk of the gains. MARA's stock dipped 5.9% following the report, reflecting broader market concerns over sector-wide pressures.
Broader data points highlight the strain:
- Average Mining Costs: As of November 3, 2025, the estimated average cost to mine one Bitcoin stood at approximately $114,233, while Bitcoin's price hovered around $101,901 on November 5, 2025, resulting in a cost-to-price ratio of 1.07—indicating that many operations are operating at or below breakeven.
- Network Hashrate: Bitcoin's hashrate hit a record 1.13 zettahashes per second (ZH/s) in October 2025, increasing competition and energy demands, which further erodes profitability for less efficient miners.
- Fee Revenue Impact: Daily fee revenue has declined from about $576,000 earlier in 2025 to $410,000, making miners more reliant on the fixed 3.125 BTC block reward and tying earnings closely to spot prices. If Bitcoin falls below $100,000, widespread miner shutdowns could occur, potentially destabilizing the network short-term.
On X (formerly Twitter), recent discussions echo these trends, with users noting that institutional liquidity is shifting off-chain (e.g., via ETFs and exchanges), reducing on-chain activity and fees, which exacerbates profitability issues. Some highlight opportunities in efficient setups, like those using low-cost renewable energy (e.g., $0.035/kWh in Norway vs. the average $0.08–$0.12/kWh), or acquiring hashrate on-demand to bypass hardware ownership. Others warn of a "strange divergence" where Bitcoin's market cap grows institutionally, but on-chain metrics remain subdued.

Overall, while select miners thrive through scale and diversification, the sector faces headwinds that could intensify without a sustained Bitcoin price recovery or fee resurgence.
