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 D3 (17.5Gh) | Metric | StrongU STU-U6 |
|---|---|---|
| — | Upfront cost (MSRP) | $5,235 |
| -$3.07 | Daily net profit | -$5.26 |
| -$1,121 | Net after 1 year | -$7,156 |
| -$2,242 | Net after 2 years | -$9,078 |
| -$3,363 | Net after 3 years | -$10,999 |
| — | 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.
