Based on BTC price of $60,342 and current network difficulty as of Jun 27, 2026. Actual results vary.
Verdict
The open-board Bitaxe Supra versus the enclosed StealthMiner. Two different approaches to desktop solo mining — minimalist PCB versus all-in-one enclosure.
Both use similar ASIC chips for solo mining. The StealthMiner offers a quieter, more polished enclosure with better thermal management. The Bitaxe Supra has a wider accessory ecosystem and larger community. Choose based on form factor preference.

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 Supra | Metric | StealthMiner |
|---|---|---|
| $89 | Upfront cost (MSRP) | $199 |
| -$0.01 | Daily net profit | -$0.02 |
| -$92 | Net after 1 year | -$206 |
| -$96 | Net after 2 years | -$214 |
| -$99 | Net after 3 years | -$221 |
| 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
Is the StealthMiner quieter than the Bitaxe?
The StealthMiner's enclosed design with optimized airflow is generally quieter. The Bitaxe with a proper heatsink is also very quiet — both are suitable for desk use.
Can both mine the same pools?
Yes. Both support standard Stratum mining connections and can be pointed at the same solo mining or regular mining pools.
