Before the crash, everyone who was bullish on Nvidia was ignorant, including Duan Yongping! They didn't understand supply and demand, didn't understand bubbles, and were utterly conceited, refusing to listen to anyone's advice. Even when Buffett liquidated $300 billion worth of US stocks, they ignored it. They knew nothing about candlestick charts! If Duan Yongping had followed my X, he would have lost at least several billion RMB less in this wave.
