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 S19k Pro | Metric | MicroBT WhatsMiner M76 |
|---|---|---|
| $313 | Upfront cost (MSRP) | — |
| -$2.25 | Daily net profit | $0.57 |
| -$1,136 | Net after 1 year | +$209 |
| -$1,958 | Net after 2 years | +$419 |
| -$2,781 | Net after 3 years | +$628 |
| Does not pay back at current rates (negative daily profit) | Payback period | — |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
