We quote per batch
Pricing and lead time change with each production batch, so every order gets a current quote rather than a list price.
Host it in Texas, or take delivery
Run it with us at $0.07 per kWh all in. No revenue share, no performance fees, and every satoshi it mines is yours.
Antminer or Whatsminer
Both run well in our facility.
Antminer (Bitmain) and Whatsminer (MicroBT) are the two dominant SHA 256 brands. Whatsminer is the line we stock, and you can buy Antminer from us too.
The S21 generation is among the most power efficient air cooled bitcoin hardware produced today, with models from 200 to 270 TH/s to fit different fleet plans.
Already own an Antminer S23?
We host your S23 fleet in Texas.
If you already own Antminer S23 units, bring them to our Southeast Texas facility. Customer owned fleets are hosted at $0.08 per kWh, all in, with a minimum of 10 units per order and a one time $30 installation fee per machine.
We confirm the cooling fit, air or hydro, for your exact units on each order. No revenue share and no performance fees: the machines and every satoshi they mine stay yours.
Antminer units we sell are factory new and carry Bitmain's manufacturer warranty. Fathom Labs is your hardware and hosting partner, not the warrantor; warranty claims go through Bitmain.
