- Antminer D7 6% more score de minage domestique (36.0 vs 34.0)
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 |
| -$7.52 | Daily net profit | -$0.43 |
| -$5,244 | Net after 1 year | -$307 |
| -$7,988 | Net after 2 years | -$463 |
| -$10,732 | Net after 3 years | -$620 |
| 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.
