Antminer is Bitmain's SHA-256 Bitcoin mining line, and the S21 generation is among the most power-efficient air-cooled hardware available today.

Mining returns depend on Bitcoin's price and network difficulty, so we quote power, not profit. To model what a given Antminer might earn under current conditions, use our profitability calculator →
Antminer vs. Whatsminer: Which Should You Run?
Antminer (Bitmain) and Whatsminer (MicroBT) are the two dominant SHA-256 brands, and both run well in our facility. Whatsminer is the line Fathom Labs stocks as an authorized dealer; Antminer we source to order. If you're weighing the two, see our Whatsminer models →
Antminer units carry Bitmain's manufacturer warranty; Fathom Labs acts as your sourcing and hosting partner, not the warrantor. See Bitmain's official Antminer line.
