Bitcoin (SHA-256) Miners

Bitcoin mining runs on the SHA-256 algorithm, and this catalog covers the full range from industrial units like the Antminer S21 XP Hyd and Whatsminer M63S+ down to solo-scale hardware like the Bitaxe NerdOCTAXE and Nerdaxe Gamma 601. The gap between these tiers is enormous: rack ASICs are measured in hundreds of TH/s, while solo units run in the KH/s to low TH/s range.

For anyone planning a serious deployment, efficiency in J/TH is the key number to compare across Antminer, Whatsminer and Canaan Avalon listings, since it determines electricity cost per unit of hashrate. Hydro-cooled variants generally offer better efficiency at the cost of a more involved plumbing setup, while air-cooled units are simpler to deploy but louder and less dense per rack.

Solo miners are a different category entirely, aimed at learning or the small chance of finding a block independently rather than steady income. Bitcoin's difficulty and price both move independently of any single hardware purchase, so revisit ROI assumptions periodically rather than treating a single calculation as final.
