Bitaxe Supra vs Nerdminer
Side-by-side specs, profitability, and home mining comparison.
Quick verdict
For most buyers the Bitaxe Supra is the stronger pick — ASIC chip produces millions of times more hashrate than ESP32-based mining. The Bitaxe Supra runs 700.0 GH/s at 17.1 J/TH; the Nerdminer runs 50.0 KH/s at 20,000,000 J/TH.

Profitability Comparison
Bitaxe Supra
Nerdminer
Based on BTC price of $64,195 and current network difficulty as of Jun 13, 2026. Actual results vary.
Verdict
The entry-level ASIC solo miner versus the ESP32 novelty miner. Both serve the solo mining community but in fundamentally different ways.
The Bitaxe Supra is a real ASIC miner producing meaningful hashrate for solo mining. The NerdMiner is an educational and decorative device. For any chance at finding a block, the Bitaxe Supra is the minimum serious option.

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 | Nerdminer |
|---|---|---|
| $89 | Upfront cost (MSRP) | $29 |
| -$0.01 | Daily net profit | -$0.00 |
| -$92 | Net after 1 year | -$30 |
| -$95 | Net after 2 years | -$31 |
| -$98 | Net after 3 years | -$32 |
| 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
Why would anyone buy a NerdMiner over a Bitaxe?
The NerdMiner costs less, has a built-in display showing mining stats, and serves as an attractive desk piece. It is about the experience and education, not the hashrate.
Can both mine Bitcoin?
Both perform SHA-256 hashing, but the Bitaxe Supra produces terahashes compared to the NerdMiner's kilohashes. Only the Bitaxe has a realistic probability of solo mining a block.
