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.
| Obelisk SC1 Dual | Metric | StrongU STU-U2 |
|---|---|---|
| — | Upfront cost (MSRP) | $499 |
| -$2.12 | Daily net profit | -$3.59 |
| -$774 | Net after 1 year | -$1,809 |
| -$1,548 | Net after 2 years | -$3,118 |
| -$2,322 | Net after 3 years | -$4,428 |
| — | 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.
