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 A3 Hydro | Metric | FluMiner T3 |
|---|---|---|
| $6,650 | Upfront cost (MSRP) | $1,601 |
| $2.00 | Daily net profit | $0.11 |
| -$5,921 | Net after 1 year | -$1,562 |
| -$5,192 | Net after 2 years | -$1,524 |
| -$4,463 | Net after 3 years | -$1,485 |
| Takes ~9.1 years to pay back at current rates | Payback period | Takes ~41.6 years to pay back at current rates |
At the default rate, the Bitdeer SealMiner A3 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.
