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 BM-S3+ | Metric | Goldshell SC Box II |
|---|---|---|
| $3,299 | Upfront cost (MSRP) | $379 |
| -$7.33 | Daily net profit | -$0.90 |
| -$5,974 | Net after 1 year | -$706 |
| -$8,649 | Net after 2 years | -$1,034 |
| -$11,324 | Net after 3 years | -$1,361 |
| 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.
