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 S15 (28Th) | Metric | StrongU Hornbill H8 Pro |
|---|---|---|
| $5,599 | Upfront cost (MSRP) | — |
| -$2.81 | Daily net profit | -$5.01 |
| -$6,625 | Net after 1 year | -$1,827 |
| -$7,651 | Net after 2 years | -$3,654 |
| -$8,677 | Net after 3 years | -$5,481 |
| Does not pay back at current rates (negative daily profit) | Payback period | — |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
