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 | Bitdeer SealMiner A2 Pro Air |
|---|---|---|
| — | Upfront cost (MSRP) | $4,000 |
| -$1.58 | Daily net profit | $0.05 |
| -$575 | Net after 1 year | -$3,983 |
| -$1,150 | Net after 2 years | -$3,967 |
| -$1,726 | Net after 3 years | -$3,950 |
| — | Payback period | Takes ~240.6 years to pay back at current rates |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
