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 K3 mini (5TH) | Metric | Goldshell KD2 |
|---|---|---|
| $288 | Upfront cost (MSRP) | $828 |
| -$0.52 | Daily net profit | -$1.78 |
| -$476 | Net after 1 year | -$1,476 |
| -$665 | Net after 2 years | -$2,124 |
| -$853 | Net after 3 years | -$2,773 |
| 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.
