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 Hyd | Metric | Bitdeer SealMiner A3 Hydro |
|---|---|---|
| $6,150 | Upfront cost (MSRP) | $6,650 |
| -$1.62 | Daily net profit | $1.79 |
| -$6,741 | Net after 1 year | -$5,998 |
| -$7,333 | Net after 2 years | -$5,346 |
| -$7,924 | Net after 3 years | -$4,694 |
| Does not pay back at current rates (negative daily profit) | Payback period | Takes ~10.2 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.
