Cost & ROI Over Time
A miner pays for itself in profit, not specs. These projections track upfront cost against one, two and three years of net earnings at $0.10/kWh.
| iBeLink K3 mini (3.5TH) | Metric | iBeLink K3 mini (5TH) |
|---|---|---|
| — | Upfront cost (MSRP) | $288 |
| -$0.31 | Daily net profit | -$0.55 |
| -$113 | Net after 1 year | -$490 |
| -$225 | Net after 2 years | -$692 |
| -$338 | Net after 3 years | -$895 |
| — | 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.
