CZ: I left OKCoin early on because of cultural and value inconsistencies; I had only been with the company for 8 months.

In the All-In podcast, CZ recounted his early career experiences to Chamath Palihapitiya, including his time at Blockchain.info (now Blockchain.com) and OKCoin, as well as his early deep understanding of the Bitcoin industry and his value choices. Joining Blockchain.info: CZ stated that the team initially consisted of only three people, with him serving as VP of Technology. The team later expanded to 18 people, but a management restructuring by the CFO led to a change in corporate culture, resulting in several developers, including CZ, voluntarily leaving. He emphasized that at Blockchain.info, he learned the concepts of remote work, paying salaries in Bitcoin, and how to achieve rapid user growth to approximately 2 million through "guerrilla" marketing (such as a 150-page post on BitcoinTalk.org). Joining OKCoin: After leaving Blockchain.info, He Yi contacted CZ to recruit him to OKCoin, initially offering 5% equity, but BTC China offered 10%, prompting OKCoin to match the offer within three hours. CZ ultimately chose to join OKCoin in Beijing as CTO, taking on greater business responsibilities. Reason for leaving OKCoin: CZ revealed that the main reason was the incompatibility of culture and values. For example, "The main issue is the incompatibility of culture and values. There are some practices that I cannot agree with. To give a simple example: when they do promotions or advertise fee discounts, the advertisements make it seem like everyone can enjoy them, but in reality, you have to actively apply for them to get them. It's not automatic. Details like these make me uncomfortable." CZ decided to leave in early 2015.
