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.
| Bitmain Antminer T19 (84Th) | Metric | Bitcoin Space Heater S19 Edition |
|---|---|---|
| $179 | Upfront cost (MSRP) | $1,299 |
| -$5.13 | Daily net profit | -$3.45 |
| -$2,053 | Net after 1 year | -$2,558 |
| -$3,926 | Net after 2 years | -$3,816 |
| -$5,800 | Net after 3 years | -$5,075 |
| 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.
