TheMinerMag, a leading crypto-market data analysis firm, has released a new report revealing that Bitcoin (BTC) mining profitability has plunged to its lowest level on record, pushing the industry into one of its most challenging periods to date.

Hash Price Drops to USD 35, Well Below Mining Costs
According to the report, the Bitcoin mining sector is now confronting its most severe revenue downturn in history.
The average hash price, an important metric representing miner revenue per unit of computing power, had remained stable at around USD 55 throughout the third quarter. However, in November, it collapsed to USD 35 following a broad market correction in the price of BTC.
At these levels, the decline in profitability has become a structural crisis, the report warns. Publicly traded major mining companies now face a median hash cost of USD 44, meaning that even miners equipped with efficient hardware and low-cost electricity are operating near breakeven.
Miners Rush to Restructure Balance Sheets
In the current environment, cost per hash has become the central metric for evaluating the financial health of mining firms.
Even the latest-generation mining machines now require over 1,000 days to recover initial investment costs, a timeline far exceeding the number of days remaining before the next Bitcoin halving—creating an unsustainable economic gap for miners.
As cash flow tightens, companies across the sector are accelerating balance sheet restructuring:
CleanSpark has turned to convertible bonds to raise capital, prioritizing debt reduction and liquidity protection.
Meanwhile, the broader industry is moving at a rapid pace toward large-scale debt financing in Q4.
Firms such as Cipher and Terawulf have notably increased their use of higher-cost senior secured notes, signaling a growing reliance on more expensive capital.
AI and HPC Revenue Still Too Small to Offset Losses
A key question now facing the sector is whether revenue streams from AI compute and HPC (high-performance computing) can meaningfully offset shrinking mining margins.
Early data indicates growth in these segments, but the scale is still far too small to counterbalance the deep decline in mining profits. As a result, the industry has entered a phase of intensified corporate consolidation and potential attrition, TheMinerMag notes.
The report concludes that unless BTC prices recover or mining economics shift dramatically, a wave of miner shakeouts may be unavoidable.
