NerdQAxe++
Based on BTC price of $64,269 and current network difficulty as of Jun 13, 2026. Actual results vary.
Verdict
Multi-chip open-source showdown. The six-chip Bitaxe Hex versus the quad-chip NerdQAxe++. More chips versus refined architecture.
The Bitaxe Hex produces more total hashrate from its six chips versus the NerdQAxe++'s four. The NerdQAxe++ may offer better value per chip. Both are serious open-source solo mining devices.

Cost & ROI Over Time
Sticker price versus what the miner actually earns back: the table below projects cumulative net profit at a $0.10/kWh electricity rate.
| Bitaxe Hex | Metric | NerdQAxe++ |
|---|---|---|
| $399 | Upfront cost (MSRP) | $349 |
| -$0.13 | Daily net profit | -$0.05 |
| -$446 | Net after 1 year | -$368 |
| -$493 | Net after 2 years | -$387 |
| -$540 | Net after 3 years | -$406 |
| 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.

Frequently Asked Questions
Which costs more to run?
The Bitaxe Hex draws more power due to its six chips. Both require 12V DC power — the Hex via XT30, the NerdQAxe++ also via XT30.
Can I run both on the same mining pool?
Absolutely. Running multiple devices on the same pool combines their hashrate for better solo mining probability.
