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 S19j Pro+ | Metric | StrongU Hornbill H8 |
|---|---|---|
| $3,200 | Upfront cost (MSRP) | $1,200 |
| -$3.79 | Daily net profit | -$5.30 |
| -$4,585 | Net after 1 year | -$3,134 |
| -$5,970 | Net after 2 years | -$5,069 |
| -$7,355 | Net after 3 years | -$7,003 |
| 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.
