Bitmain’s BM1397 will be part of the yet to be released Antminer models, the S17 and T17.
In November 2018, Bitmain restructured its Board of Directors in an effort to simplify the board for their much-desired IPO. Also in November, the mining rig manufacturer released two Antminer models.
In January 2019, Bitmain co-founders Jihan Wu and Micree Zhan Ketuan stepped down from their CEO positions but they still hold decision making powers. Also on the same month, the HKEX spotted problems in the company’s IPO proposal.
