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.
| Bitmain ANTMINER DR7 | Metric | Obelisk DCR1 |
|---|---|---|
| $1,639 | Upfront cost (MSRP) | — |
| -$1.98 | Daily net profit | -$1.16 |
| -$2,361 | Net after 1 year | -$422 |
| -$3,083 | Net after 2 years | -$844 |
| -$3,805 | Net after 3 years | -$1,267 |
| 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.
