Cost & ROI Over Time
Hardware cost is only half the story — here is how each miner's upfront price plays out against cumulative profit at a $0.10/kWh rate.
| Whatsminer M30S+ | Metric | Whatsminer M63S |
|---|---|---|
| $1,800 | Upfront cost (MSRP) | $12,000 |
| -$4.52 | Daily net profit | -$3.12 |
| -$3,450 | Net after 1 year | -$13,139 |
| -$5,100 | Net after 2 years | -$14,279 |
