In 2010, when I was job hunting, I joined a stock advisory company. After just one day of training, I left. The trainer on stage was talking about trading stocks by following the news and understanding global affairs or something like that. I just stared at the candlestick charts, completely clueless—what even is this? I couldn’t understand it at all. In 2016, I bought Bitcoin just to participate in a Ponzi scheme that used Bitcoin for transactions. It wasn’t really crypto trading; it was more like using Bitcoin to play the Ponzi game. In 2017, when the regulations came down hard and Bitcoin transactions were banned, the Ponzi scheme collapsed. But I don’t think I lost any money—I managed to withdraw my principal. After that, I didn’t get into crypto trading, just kept an eye on crypto news. Back then, those clowns like Justin Sun and He Yi hadn’t fled yet—they were still active on Weibo.
