As a London-based DeFi analyst, I’ve seen countless market cycles—but nothing prepares you for the human cost behind the numbers. This is the story of a former state-owned enterprise副厂长 who lost everything to leveraged crypto trading.

In this deep dive, I break down the psychology of leverage, the illusion of 'revenge trading', and why even rational people can spiral into financial ruin. Watch how greed, denial, and borrowed hope turned one man’s life upside down.
