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.
| Avalon A1466 | Metric | Bitdeer SealMiner A2 Pro Air |
|---|---|---|
| $4,200 | Upfront cost (MSRP) | $4,000 |
| -$3.48 | Daily net profit | -$1.83 |
| -$5,470 | Net after 1 year | -$4,668 |
| -$6,739 | Net after 2 years | -$5,336 |
| -$8,009 | Net after 3 years | -$6,004 |
| 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.
