The first person in China to buy BTC, with a net worth of 17 billion yuan on Taobao, developed tools to monitor employees' speech.

Co-founder of Bitmain, Wu Jihan, has accumulated a fortune of 17 billion yuan, making him the wealthiest post-80s 'blockchain person' and ranking 7th on the list.
Many people have never heard of the name Wu Jihan, and Baidu Baike only has three sentences to introduce him:
Wu Jihan, male, native of Beijing, co-founder of Bitmain.
In August 2019, ranked 1511th on the 2019 Forbes Global Billionaires List.
Ranked 214th on the 2019 Hurun Rich List.
However, in the crypto world, he is known as the overlord of the Bitcoin community.
Bought the first BTC on Taobao
In 2011, Wu Jihan, 25 years old, first came into contact with Bitcoin through a project: 'I spent two or three days studying the technical possibilities, and I felt that it subverted all my previous understanding.'
Wu Jihan immediately called his fren to raise funds, "Tell them there is an investment project, the risk is quite large, and the potential return is also very high. Either lose everything or make a hundredfold."
However, in the end, he did not convince several friends, but instead used all his savings to buy Bitcoin on Taobao in small amounts.
In the same year, Wu Jihan met Liu Zhipeng, an engineer at the Guangxi Land and Resources Planning Institute. He started writing science fiction novels at the age of 16, and is also known by a more popular name: Chang Jia.
Two people pooled together thousands of dollars to rent a server, set up a Bitcoin consulting website, and named it Babite. The website specializes in translating foreign articles about Bitcoin, attracting a large number of early Bitcoin players.
Wu Jihan also translated Satoshi Nakamoto's Bitcoin whitepaper into Chinese, which is still regarded as a bible by Bitcoin believers.
With a fortune of tens of millions, quit mining
After 2012, a new bull market for Bitcoin started. In the same year, Jiang Xinyu ("Roasted Cat"), a student of the 2001 class of the Youth Class of the University of Science and Technology of China, established a company in Shenzhen, announcing plans to manufacture ASIC mining rigs, and raised funds online through a "virtual IPO" project.
In July 2013, the mining farm created by "Kao Mao" company was able to mine nearly 40,000 bitcoins every month, worth tens of millions of RMB. By investing in "Kao Mao", Wu Jihan acquired a fortune worth millions.
