NerdMiner V2
Not an ASIC miner. An ESP32 microcontroller hashing in software at roughly 78 KH/s — about fifteen million times slower than a Bitaxe Gamma. It is a desk toy and a teaching tool that happens to hold a valid, non-zero lottery ticket. Buy it because it is charming, not because it will win.

What it costs, what it might win
Running costs across the site use this rate. The default is a typical household tariff — check your own bill for the real number.
The odds, honestly
At the current network difficulty of 1.262e+14, a NerdMiner V2 is expected to find a block roughly once every 2.20e+11 years. That is an average across infinite attempts, not a countdown — a block could come tomorrow, or never.
If you pooled instead
Point the same device at a normal mining pool and you would receive the statistical average steadily instead of gambling on it: about $0.0000 a month, against $0.1863 of electricity. At your electricity rate that loses money — every 3.92e-14 BTC mined costs $0.0061 in power. Buying the same BTC on an exchange would be cheaper.

The verdict
Best for: Gifts, desk decoration and understanding the protocol.
Strengths
- Costs less than a meal out
- Silent and draws 1.5W

Trade-offs
- Odds of finding a block are effectively zero even over geological time
- Not a real comparison against any ASIC device
- Solo-only, and many pools will not accept it
About NerdQAxe / NerdMiner
Community designs from shufps that scale the Bitaxe idea to four and eight ASICs on one board. NerdQAxe boards ship with the OSMU-derived NerdQAxe firmware and are the usual step up when a single-chip Bitaxe stops being enough.
