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 T17 (40Th) | Metric | Bitmain Antminer T19 (84Th) |
|---|---|---|
| $155 | Upfront cost (MSRP) | $179 |
| -$3.84 | Daily net profit | -$4.54 |
| -$1,557 | Net after 1 year | -$1,835 |
| -$2,959 | Net after 2 years | -$3,492 |
| -$4,361 | Net after 3 years | -$5,148 |
| 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.
