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 E3 (190Mh) | Metric | Antminer E9 Pro |
|---|---|---|
| — | Upfront cost (MSRP) | $3,000 |
| -$1.82 | Daily net profit | -$5.28 |
| -$666 | Net after 1 year | -$4,927 |
| -$1,332 | Net after 2 years | -$6,854 |
| -$1,997 | Net after 3 years | -$8,781 |
| — | 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.
