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 A2 Pro Hyd | Metric | Bitdeer SealMiner A3 Pro Air |
|---|---|---|
| $4,600 | Upfront cost (MSRP) | $4,895 |
| $0.10 | Daily net profit | $1.73 |
| -$4,562 | Net after 1 year | -$4,263 |
| -$4,524 | Net after 2 years | -$3,631 |
| -$4,485 | Net after 3 years | -$2,999 |
| Takes ~120.4 years to pay back at current rates | Payback period | Takes ~7.7 years to pay back at current rates |
At the default rate, the Bitdeer SealMiner A3 Pro Air 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.
