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.
| Holic H28 | Metric | NerdQAxe++ |
|---|---|---|
| — | Upfront cost (MSRP) | $349 |
| -$4.02 | Daily net profit | -$0.14 |
| -$1,467 | Net after 1 year | -$401 |
| -$2,935 | Net after 2 years | -$453 |
| -$4,402 | Net after 3 years | -$505 |
| — | 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.
