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.
| Bitmain Antminer S19 Pro Hyd (177Th) | Metric | Antminer S21 Hydro |
|---|---|---|
| $986 | Upfront cost (MSRP) | $9,500 |
| -$6.17 | Daily net profit | -$0.82 |
| -$3,237 | Net after 1 year | -$9,799 |
| -$5,488 | Net after 2 years | -$10,098 |
| -$7,739 | Net after 3 years | -$10,398 |
| Does not pay back at current rates (negative daily profit) | Payback period | Does not pay back at current rates (negative daily profit) |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
