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.
| Avalon A1566 | Metric | Holic H28 |
|---|---|---|
| $5,500 | Upfront cost (MSRP) | — |
| -$1.55 | Daily net profit | -$4.03 |
| -$6,067 | Net after 1 year | -$1,472 |
| -$6,634 | Net after 2 years | -$2,944 |
| -$7,201 | Net after 3 years | -$4,416 |
| Does not pay back at current rates (negative daily profit) | Payback period | — |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
