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 D9 | Metric | Antminer T19 |
|---|---|---|
| $3,000 | Upfront cost (MSRP) | $1,800 |
| -$6.75 | Daily net profit | -$4.54 |
| -$5,464 | Net after 1 year | -$3,457 |
| -$7,927 | Net after 2 years | -$5,114 |
| -$10,391 | Net after 3 years | -$6,771 |
| 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.
