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.
| Elphapex DG2+ | Metric | Goldshell Mini Doge II |
|---|---|---|
| $8,000 | Upfront cost (MSRP) | $258 |
| -$9.36 | Daily net profit | -$0.96 |
| -$11,416 | Net after 1 year | -$608 |
| -$14,832 | Net after 2 years | -$959 |
| -$18,248 | Net after 3 years | -$1,309 |
| 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.
