Profitability Comparison
NerdAxe
Nerdminer
Based on BTC price of $74,845 and current network difficulty as of Mar 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.

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.
