The new Antminer S21 Pro is the latest generation of Bitmain's air-cooled Bitcoin miners. The S21 Pro mines with a hashrate of 234 TH/s (SHA256) and consumes just an incredible 3531 watts — a new efficiency record for air-cooled Bitcoin mining. As a result, ongoing electricity costs are greatly minimized, which means that BTC mining still remains very profitable despite halving.

Just like its predecessors, the device is extremely robust and has a very high material quality. Thanks to the many years of experience Bitmain has gained with its miners, Bitmain miners are among the best ASICs on the market. The S21 Pro is therefore an ideal choice for all mining enthusiasts who are looking for powerful and reliable mining servers.
