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 Hydro |
|---|---|---|
| $8,800 | Upfront cost (MSRP) | $7,995 |
| $3.35 | Daily net profit | $4.20 |
| -$7,579 | Net after 1 year | -$6,461 |
| -$6,358 | Net after 2 years | -$4,926 |
| -$5,137 | Net after 3 years | -$3,392 |
| Takes ~7.2 years to pay back at current rates | Payback period | Takes ~5.2 years to pay back at current rates |
At the default rate, the Bitdeer SealMiner A3 Pro Hydro 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.
