Bitaxe Hex 302

Six BM1366 chips on one board — the first serious attempt at a multi-ASIC open-source miner. The NerdQAxe line took the idea further with better chips, and the Hex is now effectively obsolete.

The odds, honestly

At the current network difficulty of 1.262e+14, a Bitaxe Hex 302 is expected to find a block roughly once every 5.73K 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 $2.97 a month, against $8.69 of electricity. At your electricity rate that loses money — every 151 sats mined costs $0.2856 in power. Buying the same BTC on an exchange would be cheaper.

The verdict

Best for: Nobody, at current prices — listed for reference.

Strengths

  • 3 TH/s from an open-source board
  • Single power supply for six chips

Trade-offs

  • 23 J/TH, well behind BM1370 designs
  • Discontinued and hard to source
  • A NerdQAxe++ beats it on every axis

About Bitaxe

The reference open-source solo miner, designed by Skot and maintained by Open Source Miners United. Bitaxe is a hardware design rather than a company: many vendors build and sell boards from the same public schematics, so quality and price vary by builder.
