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.
| Elphapex DG 2 | Metric | Elphapex DG Hydro 1 |
|---|---|---|
| $4,680 | Upfront cost (MSRP) | $4,459 |
| -$9.12 | Daily net profit | -$14.88 |
| -$8,009 | Net after 1 year | -$9,890 |
| -$11,337 | Net after 2 years | -$15,321 |
| -$14,666 | Net after 3 years | -$20,752 |
| 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.
