About 22.7% of 22 mainstream Bitcoin mining machines run at a loss

About 22.7% of 22 mainstream Bitcoin mining machines tracked by WuBlockchain Data Center were generating negative daily net returns as of Aug. 6, 2026, showing how rising power costs, higher hash rate and efficiency gaps are squeezing older hardware even with Bitcoin near $65,000. The most efficient model's shutdown price was estimated at about $46,787, leaving top-tier ASIC miners profitable for now, but roughly five tracked models were already underwater under prevailing electricity-cost and network assumptions. The divergence points to stronger pressure on operators without low-cost power or fleet upgrades and suggests broader shutdowns would become more likely if Bitcoin moved materially closer to that break-even level.
