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.
| Antminer S9j | Metric | Avalon A1346 |
|---|---|---|
| — | Upfront cost (MSRP) | $2,800 |
| -$2.72 | Daily net profit | -$3.96 |
| -$992 | Net after 1 year | -$4,246 |
| -$1,984 | Net after 2 years | -$5,693 |
| -$2,977 | Net after 3 years | -$7,139 |
| — | 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.
