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 K7 | Metric | iBeLink BM-N1 |
|---|---|---|
| $3,500 | Upfront cost (MSRP) | — |
| -$5.08 | Daily net profit | -$5.52 |
| -$5,355 | Net after 1 year | -$2,015 |
| -$7,210 | Net after 2 years | -$4,030 |
| -$9,066 | Net after 3 years | -$6,044 |
| Does not pay back at current rates (negative daily profit) | Payback period | — |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
