It turns out I had the chance to accumulate BTC as early as 2020.

During the pandemic, I studied with a senior from high school who lived in the same neighborhood every day. Later, he went to the US to pursue a PhD in computer science and didn't return to China for four years. It wasn't until he completed his PhD and received a high-paying offer from a major American company that he came back. We talked for five hours when we met.

That's when I realized how BTC had changed his life. In 2020, he discussed smart contracts and blockchain with me, but I was solely focused on securing a spot at Tsinghua University for graduate studies, and I didn't pay it much attention.
