Sealminer A4 Series Debuts as Bitdeer Sets New Bitcoin Mining Efficiency Record
Bitdeer launched the Sealminer A4 series on April 7, 2026, with its flagship model achieving a Bitcoin mining efficiency of 9.45 J/TH. Read more.
For now, the numbers favor miners. Higher hashprice, efficient water-cooled platforms, and cheap electricity can keep margins intact even as difficulty holds steady. But this window depends on strict variables: electricity rates, network growth, and Bitcoin's price. If any of these change significantly, the current profitability ranking could reshuffle quickly. Until then, modern ASIC fleets are enjoying a rare period where scale, efficiency, and timing align.
