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.
| Innosilicon A9 ZMaster | Metric | Bitmain Antminer Z9 Mini |
|---|---|---|
| — | Upfront cost (MSRP) | $150 |
| $0.31 | Daily net profit | -$0.36 |
| +$113 | Net after 1 year | -$282 |
| +$225 | Net after 2 years | -$413 |
| +$338 | Net after 3 years | -$545 |
| — | 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.
