Bitmain, a leading manufacturer of Bitcoin mining equipment, has unveiled its latest product, the Antminer T21. This air-cooled BTC miner is designed to withstand high temperatures and supports the SHA256 mining algorithm used for cryptocurrencies like Bitcoin. With a computing power of 190 terahashes per second and an energy efficiency ratio of 19 joules per terahash, the Antminer T21 is expected to start shipping in January 2024. Bitmain also introduced a price protection plan for buyers, offering compensation in case of a decline in BTC price. This announcement was made at the Blockchain Life 2023 Forum in Dubai, where Bitmain was a diamond sponsor. The company’s new mining device joins a range of ASIC miners produced by other firms in the industry. Despite the introduction of new mining devices, the ASIC industry has faced challenges, including a significant drop in price per terahash. In the midst of this, Canaan, another major player in the industry, released its A14 series miners and sustainability-focused A1466 and A1466I miners. As the Bitcoin halving in 2024 approaches, companies like Blockstream are seeking to raise funds to purchase and store mining equipment on secondary markets.
