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.
| Innosilicon A4 Dominator | Metric | Elphapex DG2+ |
|---|---|---|
| — | Upfront cost (MSRP) | $8,000 |
| -$2.52 | Daily net profit | -$9.36 |
| -$920 | Net after 1 year | -$11,416 |
| -$1,840 | Net after 2 years | -$14,832 |
| -$2,759 | Net after 3 years | -$18,248 |
| — | 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.
