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 (5TH) | Metric | Goldshell KD5 Pro |
|---|---|---|
| $288 | Upfront cost (MSRP) | $899 |
| -$0.52 | Daily net profit | -$6.32 |
| -$476 | Net after 1 year | -$3,205 |
| -$665 | Net after 2 years | -$5,511 |
| -$853 | Net after 3 years | -$7,817 |
| 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.
