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.
| iBeLink BM-KS Max | Metric | Bitmain KAS KS7 |
|---|---|---|
| $1,799 | Upfront cost (MSRP) | $1,590 |
| -$7.76 | Daily net profit | -$5.95 |
| -$4,633 | Net after 1 year | -$3,763 |
| -$7,467 | Net after 2 years | -$5,936 |
| -$10,301 | Net after 3 years | -$8,108 |
| 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.
