Cost & ROI Over Time
Sticker price versus what the miner actually earns back: the table below projects cumulative net profit at a $0.10/kWh electricity rate.
| Bitdeer SealMiner A2 | Metric | Bitdeer SealMiner A2 Pro Air |
|---|---|---|
| $2,760 | Upfront cost (MSRP) | $4,000 |
| -$0.82 | Daily net profit | $0.08 |
| -$3,058 | Net after 1 year | -$3,969 |
| -$3,355 | Net after 2 years | -$3,938 |
| -$3,653 | Net after 3 years | -$3,907 |
| Does not pay back at current rates (negative daily profit) | Payback period | Takes ~129.3 years to pay back at current rates |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
