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 KS3 (8.3Th) | Metric | iBeLink BM-KS Max |
|---|---|---|
| $3,850 | Upfront cost (MSRP) | $1,799 |
| -$7.35 | Daily net profit | -$7.76 |
| -$6,534 | Net after 1 year | -$4,633 |
| -$9,218 | Net after 2 years | -$7,467 |
| -$11,901 | Net after 3 years | -$10,301 |
| 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.
