- Antminer D7 29% more score de minage domestique (36.0 vs 28.0)
Cost & ROI Over Time
A miner pays for itself in profit, not specs. These projections track upfront cost against one, two and three years of net earnings at $0.10/kWh.
| Antminer D7 | Metric | Bitmain Antminer Z15 |
|---|---|---|
| $2,500 | Upfront cost (MSRP) | $998 |
| -$7.52 | Daily net profit | $8.60 |
| -$5,244 | Net after 1 year | +$2,141 |
| -$7,988 | Net after 2 years | +$5,281 |
| -$10,732 | Net after 3 years | +$8,420 |
| Does not pay back at current rates (negative daily profit) | Payback period | Pays for itself in ~4 months at current rates |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
