As we mentioned earlier, when blockchain technology entered China in 2011, there were two types of people who initially contacted this technology. One was mainly mining, and from 2011 to 2014, with the rise of mining industry, a mining circle represented by bitcontinental was gradually formed; and the other group was not idle. They were obsessed with the concept of bitcoin and constantly spread knowledge in the field of blockchain to the world Most of them focus on digital currency, so they gradually set up our well-known “currency circle”. < / P > < p > in the early days, there were no organizations. They were all self-taught like Wu Jihan or Chang Jia, and they preached blockchain based on their interests. It was not until the appearance of a place that these people slowly gathered together and grew up to be the first generation of big money circle. This place was “garage coffee”. < / P > < p > when it comes to garage coffee, this place was originally a coffee shop with the theme of “entrepreneurship”. As long as entrepreneurs order a cup of coffee here, they can enjoy a whole day’s office environment and guidance, providing entrepreneurs with a space for communication and entrepreneurship. According to the truth, this place has nothing to do with blockchain. But at that time, a very famous investor in garage coffee happened to be CTO here, which made the fate of garage coffee closely linked with the blockchain, and this person was Zhao Dong. Zhao Dong, the co-founder of ink weather, had just sold all his shares when he entered the garage coffee. At that time, he believed that housing prices were at a high level and that the collapse of the financial bubble was coming. At this time, he needed to find a new investment target. At this time, he got to know Wu Gang, one of the earliest players who contacted bitcoin in China. So Wu Gang introduced him to start with 10 bitcoins and made a small profit. At this point, he was deeply in the control of bitcoin, laying the groundwork for the follow-up of the story. In March 2013, an American student named Jack came by and bought a cup of coffee. Because Jack is also a bitcoin enthusiast, he asked the clerk here “can I pay with bitcoin?”. At this time, Zhao Dong was infatuated with bitcoin, so he accepted the deal. < / P > < p > unexpectedly, this accidental event happened to be reported by CCTV. It has attracted the attention of many blockchain entrepreneurs, and everyone comes here in admiration. For example, Li Xiaolai, who once worked as a teacher in New Oriental, and Guo Hongcai, who sold pork in Shanxi, all met here. < p > < p > since then, with the bull market in 2013, the first generation of big men grew rapidly. They began to try to start a business and invest. Zhao Dong went to invest. Guo Hongcai established the mine, while Li Xiaolai set up a fund, bringing more entrepreneurs and investors into the industry. Since then, countless talents, projects and funds have come out of this circle, laying the foundation of domestic blockchain. At the beginning, their gathering place, “garage coffee”, is known as the birthplace of China’s blockchain. < / P > < p > to this day, garage coffee, although no longer accepts any payment related to digital currency. However, it still stands on an entrepreneurial street in Beijing, recording the green and astringent years of domestic blockchain development…. < / P > < p > < p > OK blockchain 60 is a popular science animation video of blockchain jointly produced by okex & sina science and technology.
