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 S19 Pro (100Th/s) | Metric | MicroBT Whatsminer M21S |
|---|---|---|
| $525 | Upfront cost (MSRP) | $650 |
| -$3.48 | Daily net profit | -$6.05 |
| -$1,796 | Net after 1 year | -$2,858 |
| -$3,067 | Net after 2 years | -$5,066 |
| -$4,338 | Net after 3 years | -$7,274 |
| 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.
