Profitability Comparison
NerdAxe
Nerdminer
Based on BTC price of $77,848 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Two very different open-source mining devices. The NerdMiner is an ESP32-based novelty miner, while the NerdAxe uses a real ASIC chip for meaningful hashrate.
The NerdAxe produces orders of magnitude more hashrate than the NerdMiner. The NerdMiner is a fun educational gadget and display piece, but it has virtually zero chance of finding a block. For actual solo mining, the NerdAxe is the minimum viable option.
Spec Deltas
The NerdAxe and Nerdminer diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- NerdAxe 999999900% more hashrate (0.5 vs 0.0 TH/s)
- Nerdminer 92% better power draw (12.0 vs 1.0 W)
- NerdAxe 100% better efficiency (24.0 vs 20,000,000.0 J/TH)
- Nerdminer 75% better weight (0.2 vs 0.1 kg)
- NerdAxe 1103% more heat output (40.9 vs 3.4 BTU/hr)
- NerdAxe 100% more home mining score (70.0 vs 35.0)
Cost & ROI Over Time
Hardware cost is only half the story — here is how each miner's upfront price plays out against cumulative profit at a $0.10/kWh rate.
| NerdAxe | Metric | Nerdminer |
|---|---|---|
| $69 | Upfront cost (MSRP) | $29 |
| -$0.01 | Daily net profit | -$0.00 |
| -$73 | Net after 1 year | -$30 |
| -$77 | Net after 2 years | -$31 |
| -$81 | 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
Can the NerdMiner actually find a block?
Theoretically yes, but the probability is astronomically small. The NerdMiner produces kilohashes while the network difficulty requires terahashes. It is best enjoyed as an educational and decorative device.
Which is better for learning about Bitcoin mining?
The NerdMiner is excellent for understanding how mining works at a conceptual level. The NerdAxe provides the same learning plus a realistic solo mining experience.
