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.
| Nerdminer | Metric | NerdQAxe |
|---|---|---|
| $29 | Upfront cost (MSRP) | $249 |
| -$0.00 | Daily net profit | -$0.12 |
| -$30 | Net after 1 year | -$293 |
| -$31 | Net after 2 years | -$337 |
| -$32 | Net after 3 years | -$380 |
| 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.
