Bitmain, a leading global manufacturer of Bitcoin application-specific integrated circuits (ASIC), has released the Antminer T21, a new air-cooled Bitcoin miner featuring a computing power of 190 TH/s, an energy efficiency ratio of 19 J/TH and is set to begin shipping in January 2024.
Bitmain took to Twitter on October 26 to announce the global debut of the Antminer T21, the company’s new air-cooling miner that can withstand ambient temperatures as high as 45 degrees Celsius.
According to Xmei Lin, the marketing director for Bitmain, the global release of the Antminer T21 took place at the Blockchain Life 2023 Forum in Dubai, where Bitmain was a “diamond sponsor.”
According to a company spokesperson, Bitmain’s brand-new mining device is anticipated to begin shipping in January 2024. The air-cooling miner supports the SHA256 algorithm for mining proof-of-work (PoW) cryptocurrencies such as Bitcoin and derived coins such as Bitcoin Cash and Bitcoin SV (BSV). The T21 provides 190 terahashes per second of computing capacity and an energy efficiency ratio of 19 joules per terahash.
Bitmain also offered Antminer T21 purchasers the chance to purchase its price protection plan, designed to assist miners if cryptocurrency prices decline. Available until November 25, 2023, the plan enables customers to buy protection against a decline in the BTC price for one, three, or six months.
Customers will receive monetary compensation if the BTC price falls below the strike for any reference day during the protected period, the company said, adding that the compensation will be paid “immediately upon the triggering event.”
Antminer T21 is one of Bitmain’s mining devices, alongside various ASIC miners manufactured by companies such as Canaan, MicroBT, Bitfury, etc.
Chinese Canaan (formerly known as Avalon) was one of the first companies to release a Bitcoin mining ASIC in January 2013, allowing consumers to mine cryptocurrency on a large scale due to a substantial increase in hashing power compared to GPU and CPU configurations.
Canaan is still producing new mining devices ten years after releasing its first mining machine. On its 10th anniversary, Canaan released its new A14 series Miners in mid-September.
Canaan introduced its environmentally conscious A1466 and A1466I miners in the Middle East on October 26. There are liquid-cooled and air-cooled options for the new miners.
Despite the efforts of companies such as Canaan and Bitmain to introduce new mining devices, the ASIC industry has faced obstacles in recent years.
As previously documented by Cointelegraph, the price per terahash of ASIC miners fell by more than 80% from its peak in 2021 to late 2022 due to the continued influx of new miners onto the market.
In August 2023, Blockstream, a blockchain technology company, sought to raise $50 million to purchase and store mining equipment on secondary markets in preparation for halving the Bitcoin supply in 2024.
