Whatsminer M21s 50t 50th/s Asic BTC Miner Machine
The successful updated powerful line of Whatsminer M21S ASICs has been released as a response to the top Bitminer miners with a large hash rate increase. Therefore, the ASIC M21S on 12-nm TSMC chips produces 50 terahashes of performance without overloading.
The manufacturer Pangolinminer recently acquired a new name - MicroBT, but retained its development of ASIC devices. Therefore, the asic M21S 50T retained the energy efficiency of the miner, as well as the design with two coolers, which drive air through the operating ASIC as quickly as possible and remove heat.
