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 Hydro | Metric | Bitdeer SealMiner A3 Pro Hydro |
|---|---|---|
| $6,650 | Upfront cost (MSRP) | $7,995 |
| $1.79 | Daily net profit | $3.95 |
| -$5,996 | Net after 1 year | -$6,554 |
| -$5,342 | Net after 2 years | -$5,112 |
| -$4,688 | Net after 3 years | -$3,671 |
| Takes ~10.2 years to pay back at current rates | Payback period | Takes ~5.5 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.
