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 | Bitmain Antminer S23 |
|---|---|---|
| $5,000 | Upfront cost (MSRP) | $4,999 |
| -$7.39 | Daily net profit | $3.05 |
| -$7,699 | Net after 1 year | -$3,885 |
| -$10,398 | Net after 2 years | -$2,770 |
| -$13,097 | Net after 3 years | -$1,656 |
| Does not pay back at current rates (negative daily profit) | Payback period | Takes ~4.5 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.
