Bitaxe Supra 401
The previous generation, built on the Antminer S19XP's BM1368. Superseded by the Gamma on every metric that matters. Only worth buying second-hand at a steep discount.
Typical street price, excluding shipping and duties.

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 Bitaxe Supra 401 is expected to find a block roughly once every 24.54K 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 $1.86 of electricity. At your electricity rate that loses money — every 35 sats mined costs $0.0612 in power. Buying the same BTC on an exchange would be cheaper.

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.
