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 T15 (23Th) | Metric | PiAxe |
|---|---|---|
| — | Upfront cost (MSRP) | $79 |
| -$2.87 | Daily net profit | -$0.02 |
| -$1,048 | Net after 1 year | -$86 |
| -$2,095 | Net after 2 years | -$92 |
| -$3,143 | Net after 3 years | -$99 |
| — | 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.
