Cost & ROI Over Time
A miner pays for itself in profit, not specs. These projections track upfront cost against one, two and three years of net earnings at $0.10/kWh.
| Bitdeer SealMiner A3 Air | Metric | Bitdeer SealMiner A3 Pro Hydro |
|---|---|---|
| $3,900 | Upfront cost (MSRP) | $7,995 |
| $0.47 | Daily net profit | $3.58 |
| -$3,727 | Net after 1 year | -$6,688 |
| -$3,554 | Net after 2 years | -$5,382 |
| -$3,381 | Net after 3 years | -$4,075 |
| Takes ~22.5 years to pay back at current rates | Payback period | Takes ~6.1 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.
