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.
| Bitmain Antminer D3 (15Gh) | Metric | Antminer D9 |
|---|---|---|
| — | Upfront cost (MSRP) | $3,000 |
| -$2.88 | Daily net profit | -$6.75 |
| -$1,051 | Net after 1 year | -$5,464 |
| -$2,102 | Net after 2 years | -$7,927 |
| -$3,153 | Net after 3 years | -$10,391 |
| — | 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.
