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 T19 Pro Hyd | Metric | Bitdeer SealMiner A3 Pro Air |
|---|---|---|
| $2,599 | Upfront cost (MSRP) | $4,895 |
| -$3.85 | Daily net profit | $1.85 |
| -$4,006 | Net after 1 year | -$4,218 |
| -$5,413 | Net after 2 years | -$3,541 |
| -$6,820 | Net after 3 years | -$2,864 |
| Does not pay back at current rates (negative daily profit) | Payback period | Takes ~7.2 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.
