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.
| Antminer D7 | Metric | Bitmain Antminer Z9 Mini |
|---|---|---|
| $2,500 | Upfront cost (MSRP) | $150 |
| -$7.51 | Daily net profit | -$0.36 |
| -$5,241 | Net after 1 year | -$281 |
| -$7,981 | Net after 2 years | -$413 |
| -$10,722 | Net after 3 years | -$544 |
| 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.
