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.
| Antminer S19 Pro+ | Metric | Bitdeer SealMiner A3 Pro Hydro |
|---|---|---|
| $3,000 | Upfront cost (MSRP) | $7,995 |
| -$3.70 | Daily net profit | $4.22 |
| -$4,349 | Net after 1 year | -$6,453 |
| -$5,698 | Net after 2 years | -$4,912 |
| -$7,047 | Net after 3 years | -$3,370 |
| Does not pay back at current rates (negative daily profit) | Payback period | Takes ~5.2 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.
