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.
| BW L21 | Metric | Goldshell Mini-DOGE |
|---|---|---|
| — | Upfront cost (MSRP) | $298 |
| -$2.28 | Daily net profit | -$0.56 |
| -$832 | Net after 1 year | -$502 |
| -$1,664 | Net after 2 years | -$706 |
| -$2,497 | Net after 3 years | -$910 |
| — | 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.
