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-K1 | Metric | iBeLink K3 mini (5TH) |
|---|---|---|
| $9,855 | Upfront cost (MSRP) | $288 |
| -$1.81 | Daily net profit | -$0.52 |
| -$10,517 | Net after 1 year | -$476 |
| -$11,179 | Net after 2 years | -$665 |
| -$11,840 | Net after 3 years | -$853 |
| 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.
