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 (19.3Gh) | Metric | Bitmain Antminer D9 (1770Gh) |
|---|---|---|
| — | Upfront cost (MSRP) | $1,030 |
| -$3.24 | Daily net profit | -$6.75 |
| -$1,182 | Net after 1 year | -$3,494 |
| -$2,365 | Net after 2 years | -$5,957 |
| -$3,547 | Net after 3 years | -$8,421 |
| — | 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.
