- Wu, Jihan; stepped down as CEO in 12-2018, remained as co-chairs. Came back as CEO in 10-2019. (Was part of Hong Kong consensus). Got bought out for $600M (30-12-2020).
- Zhan, Micree; stepped down as co-CEO in 12-2018, remained as co-chairs. Kicked out of the company in 10-2019. (Was part of Hong Kong consensus)
- Had quite some power struggles in 2019:
"CoinDesk has obtained and verified a partial transcript from the hourlong meeting on Tuesday. In it, Jihan Wu, a co-founder of Bitmain who started the company with Zhan in 2013, explained to all employees why he thought it was necessary to oust his long-time partner and former co-CEO.
After stepping down from day-to-day management in December 2018, Wu returned Tuesday as chairman of the company and executive director of the Beijing Bitmain subsidiary. Earlier in the day, Wu notified staff that Zhan had been dismissed from all his roles, effective immediately. During the subsequent all-hands meeting, he described a falling-out between the two executives late last year. "Zhan escalated what should be a disagreement on an ordinary company business decision to the level of power struggle,” Wu told the staff. Wu said in Tuesday’s meeting that he and Zhan have butted heads since 2015.
However, things came to a head in December 2018 when Bitmain decided on a round of major layoffs. Wu pushed for the layoffs, while Zhan initially resisted. According to Wu, he and three other founding members of Bitmain tried to persuade Zhan to reach an unanimous decision on the layoffs, which Wu and others viewed as necessary for saving the company. Zhan remained unconvinced, however, and tried to rally other senior and mid-level management against the layoff plan, Wu said, only to find out that most supported it. The two came to an agreement to both step down as co-CEOs and Bitmain moved ahead with the layoffs.
But even with bitcoin’s price rebound in 2019, Wu said the company didn’t fully seize the moment. “Our mining equipment’s market share is declining,” he said. “Our mining pools’ dominance is also declining.” Indeed, Bitmain’s major rival miner makers including Canaan, WhatsMiner and InnoSilicon have all been able to increase sales following the market boom this year. Meanwhile, BTC.com and Antpool, Bitmain’s flagship mining pools, lost their long-time dominant positions to Poolin – founded by former BTC.com creators – and F2Pool. Poolin and F2pool are currently the top two mining pools in the world, based on the real-time hash rate distribution.
However, a major question remains unanswered: How did Bitmain manage to dismiss Zhan from all of his roles given that he was the chairman and major shareholder?"
- Gadi Glikberg, who headed the Israeli company and served as a VP at Bitmain lost his position when Bitmain had to shut down the development center in Israel due to the bearmarket in 2018. Months after it filed an application to go public on the Hong Kong Stock Exchange, Beijing-based cryptocurrency mining giant Bitmain is undergoing a series of business changes that extend even to its China offices: “It’s affirmative. The layoff will start next week and involves more than 50 percent of the entire Bitmain’s headcount,” replied one verified Bitmain staff on Maimai to the thread. “Some departments have to be let go entirely,” replied another verified Bitmain employee on the same thread. “Now Bitmain has about 3,100 people, even several hundreds more than what was disclosed in the IPO prospectus in September. But there were only about 1,000 people at the beginning of the year,” the source said, adding the growth rate is like two to three times in general.

The investigation is likely over allegations of intellectual property infringement by the firm related to the technology of its rival Beijing-based crypto mining giant Bitmain, according to one source close to MicroBT with knowledge of the matter. Yang was formerly processor design director at Bitmain, responsible for developing the firm’s flagship AntMiner S7 and S9 models around 2016. However, he left the company and raised over $20 million to found MicroBT – which produces the WhatsMiner range of mining devices – after discussions with Zhan and Wu for stock options fell through."
"Prior to the December 2018 shake-up, Zhan held 36 percent of Bitmain’s holding company while Wu had just 20.25 percent, according to Bitmain’s 2018 IPO filing in Hong Kong citing data from September 2018.
Other major shareholders include founding members Yuesheng Ge (4.18 percent), Zhaofeng Zhao (6.26 percent), and Yishuo Hu (4.18 percent), as well as a trust that held 18.47 percent as the company’s employee stock-option incentive.
Other major external shareholders include Sequoia China Capital (2.7 percent), Richway Investment Limited (1.17 percent) and Sinovation (1.13 percent)."
