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 S19 Hydro | Metric | Avalon A1446 |
|---|---|---|
| $5,000 | Upfront cost (MSRP) | $3,200 |
| -$7.49 | Daily net profit | -$3.16 |
| -$7,733 | Net after 1 year | -$4,355 |
| -$10,467 | Net after 2 years | -$5,510 |
| -$13,200 | Net after 3 years | -$6,665 |
| Does not pay back at current rates (negative daily profit) | 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.
