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 S19j (90Th) | Metric | Bitmain Antminer S19j Pro (104Th) |
|---|---|---|
| $405 | Upfront cost (MSRP) | $398 |
| -$4.41 | Daily net profit | -$3.44 |
| -$2,014 | Net after 1 year | -$1,655 |
| -$3,623 | Net after 2 years | -$2,912 |
| -$5,231 | Net after 3 years | -$4,168 |
| 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.
