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 DR3 | Metric | Bitmain Antminer DR5 (34Th) |
|---|---|---|
| — | Upfront cost (MSRP) | $2,100 |
| -$3.10 | Daily net profit | -$3.10 |
| -$1,133 | Net after 1 year | -$3,231 |
| -$2,266 | Net after 2 years | -$4,361 |
| -$3,398 | Net after 3 years | -$5,492 |
| — | 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.
