Cost & ROI Over Time
Hardware cost is only half the story — here is how each miner's upfront price plays out against cumulative profit at a $0.10/kWh rate.
| Bitmain Antminer E11 (9.5Gh) | Metric | Antminer KS3 |
|---|---|---|
| $1,902 | Upfront cost (MSRP) | $8,000 |
| -$5.93 | Daily net profit | -$8.06 |
| -$4,066 | Net after 1 year | -$10,942 |
| -$6,229 | Net after 2 years | -$13,885 |
| -$8,393 | Net after 3 years | -$16,827 |
| 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.
