The Antminer S21 is the innovative current model generation of Bitmain Bitcoin miners, which mine BTC using the SHA-256 algorithm with a maximum hash rate of 200 TH/s. With its very high output of 200 TH/s, the S21 only consumes an incredible 3500W, making the new S21 by far one of the best miners ever built. Due to its high performance with very low power consumption, the S21 also sets new energy standards for a Bitcoin miner and is incredibly efficient.
The device is extremely robust and reliable and was developed for use under tough conditions. Thanks to the many years of experience Bitmain has gained with its miners, Bitmain miners are the best ASICs on the market. The S21 is therefore the most popular choice for all miners (whether entry-level miners or large groups of investors) looking for powerful and reliable mining servers.
