Telegram : @zeusmining_presalesIn October 2023, Bitmain launched a new air-cooled BTC ASIC mining equipment Antminer T21, which uses the SHA-256 algorithm for mining. The miner's production capacity is as high as 190Th/s and maintains an efficiency ratio of approximately 19.0J/TH, and power consumption is 3610W. It is the latest in a series of devices following the S21 series and is expected to ship in the first quarter of 2024. It is understood that the unique feature of Antminer T21 is that users can flexibly adjust between NEM and HEM modes to optimize their mining operations.
