In 2010, a 16-year-old Chinese prodigy named Zhou Tong bought Bitcoin for $10. His fascination with decentralized currency led him to create Bitcoinica — the first cryptocurrency margin trading platform — in just four days. At its peak, Bitcoinica processed $40 million monthly, becoming the second-largest exchange after Mt. Gox. Yet, a series of devastating hacks resulted in the loss of 101,554 BTC (worth ~$6.8 billion today). Here’s the untold story of ambition, innovation, and irreversible security failures.
