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.
| Obelisk DCR1 | Metric | Obelisk SC1 Slim |
|---|---|---|
| — | Upfront cost (MSRP) | $2,600 |
| -$1.16 | Daily net profit | -$1.06 |
| -$422 | Net after 1 year | -$2,987 |
| -$844 | Net after 2 years | -$3,374 |
| -$1,267 | Net after 3 years | -$3,761 |
| — | 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.
