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.
| Canaan AvalonMiner 1146 Pro | Metric | StealthMiner |
|---|---|---|
| $1,150 | Upfront cost (MSRP) | $199 |
| -$5.59 | Daily net profit | -$0.01 |
| -$3,192 | Net after 1 year | -$204 |
| -$5,234 | Net after 2 years | -$210 |
| -$7,276 | 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.
