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.
| Bitaxe Hex | Metric | NerdOctaxe Gamma |
|---|---|---|
| $399 | Upfront cost (MSRP) | $599 |
| -$0.11 | Daily net profit | -$0.19 |
| -$438 | Net after 1 year | -$669 |
| -$478 | Net after 2 years | -$739 |
| -$517 | Net after 3 years | -$810 |
| 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.
