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 L3+ (504Mh) | Metric | Goldshell Mini-DOGE III |
|---|---|---|
| $165 | Upfront cost (MSRP) | $499 |
| -$1.92 | Daily net profit | -$1.20 |
| -$866 | Net after 1 year | -$937 |
| -$1,567 | Net after 2 years | -$1,375 |
| -$2,267 | Net after 3 years | -$1,813 |
| 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.
