The blockchain field is generally divided into three major directions: project parties, exchanges, and mining machine vendors. CEOs who start businesses in these three directions have different life experiences.
In addition to the media, the departure of company CEOs in other fields seems to be more frequent. They either chose to leave due to internal disputes in the company, or embarked on a new journey to find another spring in their careers because of their personal career planning.

"One size fits all" Li Shufei, Xu Mingxing who sends blessings
When it comes to keywords such as the CEO of the exchange and resignation, people often think of OKEx. Because just like in "Friends", the male protagonist Ross was labeled as the "divorce king" because he experienced three failed marriages. OKEx, which has experienced two CEO resignations and many executive resignations, is undoubtedly also left in people's hearts. relatively bad impression.
In 2011, Xu Mingxing came into contact with Bitcoin for the first time when he was chasing the American drama "The Good Wife", and later established the digital trading platform OKCoin in 2013.
In order to break through the market quickly, Mingxing Xu ingeniously chose Litecoin as a breakthrough point, launched Litecoin trading pairs in November 2013, exempted Litecoin transaction fees, and vigorously publicized with the gimmick of low currency prices and high profits.
One month later, OKCoin announced that the transaction volume of Litecoin reached 8.5 million, and the daily processing amount reached 3 billion yuan, setting a record for the global digital currency trading platform at that time.
Since then, OKCoin has started its own trading life, and its trading volume has been rising steadily. In China and even in the world, OKCoin's trading business has leapt to the forefront.
However, within a few years of good times, "September 4th" came. In order to avoid policy-level supervision, OKCoin established OKEx, with Xu Mingxing as CEO.
In December 2017, OKEx announced the completion of tens of millions of dollars in financing; since January 2018, OKCoin has launched more than 20 ICO projects within one month.
But in February 2018, Xu Mingxing resigned as OKEx CEO and was replaced by Li Shufei.
According to public information, Li Shufei is from Hong Kong. He joined OKCoin in 2016. After entering the company, he non-stop made B-round financing, established a corporate management team, and then established an international team.
Since then, Xu Mingxing has seldom made public remarks. He retreated behind the scenes in OK's internal communication group, and even said "donate to the country at any time in the future". OK began to take the initiative to embrace supervision, and Xu Mingxing was responsible for the development and application of OKChain full-time.
However, blessings come without pairs, and misfortunes never come singly. Just 3 months after Li Shufei took over this position, on May 14, 2018, he announced in Moments that he would leave OK Group and resign from OKEx CEO, OKCoin CFO and other positions.

This news was once topped in Baidu's hot search. Among the real-time hot spots, "OKEX Li Shufei resigned" ranked eighth. Two days later, he himself published an article saying that he "didn't expect" to be on the hot search.
There are different opinions in the industry about the fact that the new official will leave only three months after taking office. Three days later, Li Shufei published a long article in response to the controversy, in which he stated that Xu Mingxing was "not easy to get along with" and that he was "not used to trusting people."
In addition, Li Shufei also mentioned that he wanted to "try other options", so he simply "one size fits all" and chose to leave this "whampoa military academy in the currency circle".
And the "other options" in his mouth are OKEx's old rival Huobi.com. On May 21, 2018, Huobi publicly announced that Li Shufei will serve as Secretary of the Board of Directors and Vice President of International Business Development of Huobi.
Behind the blunt blessing, Xu Mingxing must have jumped out of anger for Li Lin's unkind "poaching" behavior.

Zhou Zhengjun resigned from the live broadcast, and it was Yang Ning who ran away with money
Compared with Li Shufei, Zhou Zhengjun, who also resigned with a high profile, went more "dramatically".
Later, in the TTT official community, some people questioned that Zhou Zhengjun had run away.

In fact, behind Zhou Zhengjun and the TTT project he founded, there is an extremely glorious history.
According to public information, Zhou Zhengjun is a "blockchain software and chip research and development expert with more than 20 years of research and development experience." The mobile browser that he once led the research and development of was acquired by Qihoo 360 and became the latter's core technology.
Later, Zhou Zhengjun founded the TTT alliance chain project. Because "making money is relatively slow", he established the TrustNote Foundation at the end of 2017 to conduct an ICO, and then started private placement in early 2018. The private placement price is 1ETH = 8500TTT.
Relying on the contacts accumulated over the years in the industry, Zhou Zhengjun led TTT to raise 20,000 ETH in 2 days. According to the price at that time, one ETH could reach tens of thousands of yuan at the highest. TTT raised 200 million yuan in 2 days. So widely known.
According to a previous report by "Daily Economic News", after TTT completed financing, some executives even lamented that "there is so much money that they don't know how to spend it".
This is Zhou Zhengjun's highlight moment and also the pinnacle of TTT's development. But the speed of the turning point is as fast as the speed of their financing.
In the previously released white paper, TTT stated that the project will be listed on major exchanges such as Binance and OKEx before March 2, 2018, but it was not until April 25 that TTT was launched on a small exchange Bit-Z. On-line trading, the market opened at 0.4 yuan. After hitting a high of 1.12 yuan, it fell all the way. By the time Zhou Zhengjun announced his resignation, the TTT quotation was 3 points.
As the price of the currency fell all the way, TTT's operation team also began to have problems. According to a previous report by "Daily Economic News", many employees who participated in the private placement at that time approached the company's director of operations and wanted to refund the coins; the director of operations approached Zhou Zhengjun, but Zhou Zhengjun said, "Is it necessary to come to me for this matter?"
As a result, under such contradictions, the entire operation team resigned. But in the face of such a situation, Zhou Zhengjun also made a lot of efforts, and even recruited pyramid schemes, intending to raise the price of the currency, but due to various reasons, he failed in the end.
Currency prices kept falling, investors came to make trouble, and the team almost disbanded. It was under such tremendous pressure that Zhou Zhengjun released financial data in the live broadcast and announced his resignation as CEO.
In an interview with People's Daily Online, Zhou Zhengjun once said that the current "blockchain technology is not yet mature." Perhaps, after a trip to the chaotic currency circle, Zhou Zhengjun still wants to return to his original intention, and he may not necessarily be a research and development personnel who focuses on technology.
As for the same project, Yang Ning is much more impetuous than Zhou Zhengjun.
According to public information, on January 20, 2018, ZB.com opened the CDC deposit service. On the day of the event, the announcement showed that "the user with the largest trading volume can get a Maserati SUV", and then the price of CDC tokens skyrocketed by 400%. Since then, the CDC has entered people's field of vision.
But what is strange is that the white paper of CDC was only released in February. The information in it shows that CDC is positioned as "blockchain + consumption", and the "director-general" is Yang Ning, the former president of KongZhong. It can be said that Yang Ning is the CEO of CDC .
Two months later, CDC first stopped updating on Twitter. After the CDC/BTC trading volume hit a record high, it shrank rapidly the next day: this means that CDC has experienced a large number of selling behaviors in the secondary market;
The CDC, which opened high and went low, successfully passed the Huobi HADAX vote and was about to be listed on the night before, it was revealed by netizens that two transfers occurred in its contract address, worth 600 million and 750 million respectively;
In November 2018, Huobi Global stopped all CDC transactions and recharge services on the platform. At the same time, the CDC team was disbanded.
On November 6, Sanyan Finance and Economics interviewed Yang Ning overnight. He confirmed that the team had been disbanded, and said that "entering the currency circle is the most regrettable thing in my career."
However, in response to such rhetoric, users have said that Yang Ning is a "liar", because some media broke out that Yang Ning and his team bought two wineries in France after they left the market and cashed out at high positions.
Wu Jihan who was "forced into the palace": Run away to find a second spring
Compared with the resignation of the above two people, the news of Wu Jihan's departure from Bitmain caused a storm in the industry no less than a typhoon.
On December 28, 2018, according to Odaily news, Jihan Wu and Ketuan Zhan may step down as CEO of Bitmain at the same time soon. Although until now, the CEO of Bitmain is still Wu Jihan according to the public information, but as the saying goes, there are no waves without waves, and there are still speculations about his resignation in the industry.
And Wu Jihan himself, has also painted a rich and colorful stroke in the history of Bitcoin.
According to a previous blockchain report, in 2011, Wu Jihan came into contact with bitcoin for the first time, was moved by its liberal core, translated the white paper of bitcoin, scolded Ripple on Weibo for not being open source, and promoted bitcoin as " Anarchist Paradise".
In 2012, relying on investing in the stocks of the mining machine genius "Roasted Cat", he had a net worth of tens of millions. Then he quit his investment bank job in 2013, "All in" Bitcoin, recruited Zhan Ketuan, and founded Bitmain in 2013.
After the company was founded, Wu Jihan led Bitmain to develop mining chips, established a trinity product system of "mining machine, mine farm, and mining pool", and became an unshakable giant in the Bitcoin mining circle by relying on early market dividends.
But such dividends did not take long. The long bear market in 2018 made the market calm down. At the same time, miners found that Bitcoin mining became more and more difficult, and mining profits were far from enough to cover the cost of purchasing mining machines. As a result, Bitmain, whose main business is mining machine sales, has been hit hard.
At its peak, Bitmain had more than 3,000 employees. But on December 29, 2018, according to BITCOINMAGAZINE (Bitcoin Magazine), Bitmain was exposed to crazy layoffs, with a layoff ratio as high as 85%. This news was later confirmed by a Bitmain employee;
On February 26, 2019, a former Bitmain employee said that there was a "unilateral agreement" between Zhan Ketuan and Wu Jihan: for a period of six months, if Bitmain's AI business (led by Zhan Ketuan) can generate enough For cash flow, keep the AI business line. The other party stated that Ketuan Zhan wanted to "prove that his choice was right and the other supervisor's choice was wrong" to force Gong Wu Jihan
Perhaps, Wu Jihan himself realized that he had reached the point where he had to leave. Therefore, also on February 26, Wu Jihan registered a cryptocurrency financial service start-up company in Singapore with the full English name "MATRIX TECH PTE. LTD.", and the Chinese name "Matrix Endpoint", which was launched on July 8 its website.
As for this company called Matrix for short, dozens of its 100 employees come from Bitmain. The company's main business is OTC trading services and digital asset management and lending.
However, these two business tracks are already overcrowded. Even with the reputation of the former "mining tyrant" Wu Jihan, how to build a better business model and seek market recognition for it will surely go through a period of essential exploration. process.
Most of the CEOs who left the original company chose to stay in the blockchain and cryptocurrency industry, looking for the next breakthrough.
After having previous experience, they may all be able to find a new and more precise direction, and among them, there may be a certain star-level project hidden in the future.
