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 E9 (2.4Gh) | Metric | Antminer KS3 |
|---|---|---|
| $1,000 | Upfront cost (MSRP) | $8,000 |
| -$6.13 | Daily net profit | -$8.06 |
| -$3,239 | Net after 1 year | -$10,943 |
| -$5,478 | Net after 2 years | -$13,885 |
| -$7,717 | Net after 3 years | -$16,828 |
| 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.
