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 S23 Immersion (368Th) | Metric | Whatsminer M63S |
|---|---|---|
| $5,899 | Upfront cost (MSRP) | $12,000 |
| $3.59 | Daily net profit | -$3.13 |
| -$4,589 | Net after 1 year | -$13,144 |
| -$3,278 | Net after 2 years | -$14,288 |
| -$1,968 | Net after 3 years | -$15,432 |
| Takes ~4.5 years to pay back at current rates | 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.
