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.
| Avalon A1446 | Metric | StealthMiner |
|---|---|---|
| $3,200 | Upfront cost (MSRP) | $199 |
| -$3.16 | Daily net profit | -$0.01 |
| -$4,354 | Net after 1 year | -$204 |
| -$5,509 | Net after 2 years | -$210 |
| -$6,663 | Net after 3 years | -$215 |
| 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.
