The profitability of Bitcoin mining has sharply declined due to a combination of falling BTC prices and record-high network difficulty. A new report estimates that 15-20% of the global mining fleet is now operating at a loss, placing significant financial strain on operators using older equipment and pushing some toward diversification.
A significant portion of Bitcoin miners are now unprofitable as hash prices collapse. CoinShares estimates that 15-20% of the global mining fleet operates at a loss with hash prices at $28-30 per PH/day.
Bitcoin fell nearly 31% in Q4 2025, dropping from around $126,000 to $86,000. This price correction coincided with near-record network hash rates, driving hash prices to post-halving lows.
Miners using mid-generation hardware faced negative cash flow without ultra-cheap electricity. CoinShares found that the weighted average cost of production for public miners reached $79,995 per Bitcoin in Q4 2025.
The report linked this to higher electricity costs and increased depreciation from new infrastructure. It identified three consecutive negative difficulty adjustments in late 2025, a rare signal of miner capitulation.
Operators with legacy S19-series equipment were particularly impacted. Winter energy costs and grid curtailments increased unprofitable mining hours for these units.
The pressure has forced some miners to diversify toward AI and high-performance computing workloads. These alternatives promise higher and more stable returns compared to cyclical Bitcoin mining.
Despite the strain, the network hash rate has shown resilience. It peaked near 1,160 EH/s in October 2025 before dipping roughly 10% by early 2026.
The network stabilized near 1,020 EH/s by early March 2026. This indicates strategic miners with low-cost energy or next-generation ASICs continue to operate profitably.
Publicly listed miners have reduced their BTC holdings in response to tight margins. Companies like Core Scientific, Bitdeer, and Riot have all liquidated significant amounts from their treasuries.
Recovery in hash prices remains closely tied to BTC price movements. A steady price above $70,000 could alleviate pressure, while prolonged weakness may trigger further miner capitulation.
