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.
| Antminer KS5 Pro | Metric | Goldshell E-KA1M |
|---|---|---|
| $15,000 | Upfront cost (MSRP) | $910 |
| -$6.80 | Daily net profit | -$4.12 |
| -$17,484 | Net after 1 year | -$2,415 |
| -$19,967 | Net after 2 years | -$3,919 |
| -$22,451 | Net after 3 years | -$5,424 |
| 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.
