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.
| Bitmain Antminer L7 (9.05Gh) | Metric | Goldshell Mini DOGE III (500Mh) |
|---|---|---|
| $750 | Upfront cost (MSRP) | $749 |
| -$7.82 | Daily net profit | -$0.62 |
| -$3,606 | Net after 1 year | -$977 |
| -$6,461 | Net after 2 years | -$1,205 |
| -$9,317 | Net after 3 years | -$1,432 |
| 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.
