- Obelisk SC1 10% more home mining score (31.0 vs 34.0)
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.
| Innosilicon S11 SiaMaster | Metric | Obelisk SC1 |
|---|---|---|
| $2,000 | Upfront cost (MSRP) | — |
| -$3.09 | Daily net profit | -$1.18 |
| -$3,126 | Net after 1 year | -$431 |
| -$4,252 | Net after 2 years | -$862 |
| -$5,378 | Net after 3 years | -$1,292 |
| 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.
