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.
| Bitmain Antminer S23 Hyd | Metric | Bitdeer SealMiner A3 Hydro |
|---|---|---|
| $12,995 | Upfront cost (MSRP) | $6,650 |
| $7.64 | Daily net profit | $1.79 |
| -$10,207 | Net after 1 year | -$5,998 |
| -$7,419 | Net after 2 years | -$5,347 |
| -$4,630 | Net after 3 years | -$4,695 |
| Takes ~4.7 years to pay back at current rates | Payback period | Takes ~10.2 years to pay back at current rates |
At the default rate, the Bitmain Antminer S23 Hyd 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.
