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.
| Antminer T19 | Metric | MicroBT Whatsminer M20S |
|---|---|---|
| $1,800 | Upfront cost (MSRP) | $66 |
| -$4.41 | Daily net profit | -$5.52 |
| -$3,411 | Net after 1 year | -$2,080 |
| -$5,023 | Net after 2 years | -$4,094 |
| -$6,634 | Net after 3 years | -$6,108 |
| 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.
