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-S3 Siacoin Miner | Metric | Goldshell SC5 Pro (8.8Th) |
|---|---|---|
| $1,330 | Upfront cost (MSRP) | — |
| -$6.77 | Daily net profit | -$4.56 |
| -$3,800 | Net after 1 year | -$1,666 |
| -$6,270 | Net after 2 years | -$3,332 |
| -$8,739 | Net after 3 years | -$4,998 |
| Does not pay back at current rates (negative daily profit) | Payback period | — |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
