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.
| VOLCMINER D3 | Metric | Elphapex DG2 Mini |
|---|---|---|
| $5,990 | Upfront cost (MSRP) | $999 |
| -$8.59 | Daily net profit | -$1.27 |
| -$9,126 | Net after 1 year | -$1,463 |
| -$12,262 | Net after 2 years | -$1,927 |
| -$15,397 | Net after 3 years | -$2,392 |
| 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.
