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.

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.

Hardware plus power. This is what the ticket costs you, win or lose.

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
  • Genuinely useful for learning how mining and stratum work

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.
