The astonishing true story of the coal miner's daughter who took on the creators of the world's biggest financial fraud and helped the FBI to convict them A teenage mother, today a young grandmother, Jen McAdam was a victim of the OneCoin global cryptocurrency fraud, which stole tens of billions of dollars from ordinary people around the world. Unlike Madoff or Enron, who relieved the world's wealthiest investors of their cash, the exploiting genius of the OneCoin scam was targeting the poorest people in the world, the "unbanked"—those who struggled to live or get mainstream banking support. The fraudsters believed their victims couldn't and wouldn't fight back. They didn't reckon on Jen McAdam, a modern-day Erin Brockovich. Jen's father left her £15,000 when he died: his savings from living a careful life in a small Scottish mining town. She was digitally savvy, and she had heard of people making fortunes with Bitcoin. When she saw the promotional material for OneCoin—she was entranced. Only months later, she realized she would never see her money again. Jen was one of the only victims worldwide to fight back. Despite terrifying attempts to shut down both her and her growing support groups, she fought tirelessly for justice for herself, her family and friends, and the millions around the world who lost everything, in some cases even their lives. This is a true David-and-Goliath story to give us all a message of hope about the power we as individuals can have, even when things seem hopeless.
