Lao Chen is 52 this year and has worked in the factory for 30 years. Before retiring, he invested the 400,000 yuan meant for his retirement into BTC futures, hoping to give his wife a better house. On the day he got liquidated, he stood on the rooftop for two hours, and in the end his coworkers pulled him back. His wife said, “If the money is gone, that’s fine—at least we still have people.”
