Cost & ROI Over Time

Hardware cost is only half the story — here is how each miner's upfront price plays out against cumulative profit at a $0.10/kWh rate.

Bitmain Antminer S23 Immersion (442Th) Metric Bitdeer SealMiner A3 Pro Air
$8,800 Upfront cost (MSRP) $4,895
$3.34 Daily net profit $1.85
-$7,579 Net after 1 year -$4,221
-$6,358 Net after 2 years -$3,547
-$5,138 Net after 3 years -$2,873
Takes ~7.2 years to pay back at current rates Payback period Takes ~7.3 years to pay back at current rates

At the default rate, the Bitmain Antminer S23 Immersion (442Th) reaches break-even first — but plug in your own electricity cost above, since payback shifts sharply with it.

Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
