Cost & ROI Over Time
Hardware cost is only half the story — here is how each miner's upfront price plays out against cumulative profit at a $0.10/kWh rate.
| Antminer S19 Hydro | Metric | Antminer S19j Pro+ |
|---|---|---|
| $5,000 | Upfront cost (MSRP) | $3,200 |
| -$7.34 | Daily net profit | -$3.80 |
| -$7,678 | Net after 1 year | -$4,586 |
| -$10,355 | Net after 2 years | -$5,972 |
| -$13,033 | Net after 3 years | -$7,358 |
| 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.
