NerdQAxe+

The BM1368 predecessor to the ++. Half the hashrate and 24 J/TH instead of 15 — and now that the ++ has fallen in price, remaining stock of the + often lists for more than its own successor. Impossible to justify new; fine second-hand.

The odds, honestly

At the current network difficulty of 1.262e+14, a NerdQAxe+ is expected to find a block roughly once every 6.87K 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 $2.47 a month, against $7.45 of electricity. At your electricity rate that loses money — every 126 sats mined costs $0.2448 in power. Buying the same BTC on an exchange would be cheaper.

The verdict

Best for: Used buyers who find one well under $200.

Strengths

  • Same firmware and enclosure as the ++
  • Plentiful on the used market

Trade-offs

  • 24 J/TH — 60% worse than the ++
  • Frequently priced above the ++ that replaced it
  • Being wound down

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.
