Early participants in the BTC circle each have their own stories. Xu Mingxing was the earliest to get involved, learning about Bitcoin in 2011 through American TV shows. Sun Yuchen followed closely, purchasing his first batch of BTC on Taobao in 2012. By 2013, this year became a pivotal moment in the cryptocurrency world—Li Xiaolai chose to borrow money to increase his positions, Bao Er Ye completely shifted from selling pork to the crypto circle, Li Lin was inspired to start a business due to frustrating purchasing experiences, and He Yi became the guide for Zhao Changpeng's entry into the crypto world. It wasn't until 2015 that Zhao Changpeng officially entered the scene—his approach was quite decisive—selling his apartment to go all-in. The choices of these early participants witnessed Bitcoin's transition from the fringe to the mainstream. Different entry times and participation methods ultimately point to the same conclusion: timing and determination often determine the differences in returns in the field of crypto assets.
