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.
| Bitmain Antminer S7-LN | Metric | NerdQAxe++ |
|---|---|---|
| — | Upfront cost (MSRP) | $349 |
| -$1.57 | Daily net profit | -$0.14 |
| -$575 | Net after 1 year | -$401 |
| -$1,149 | Net after 2 years | -$453 |
| -$1,724 | Net after 3 years | -$505 |
| — | 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.
