The astonishing true story of the Scottish coal miner’s daughter who took on the Mafia-backed creators of the world’s biggest financial fraud and helped the FBI to convict them

Soon to be a major Hollywood film directed by Scott Z Burns

‘In the 1990s, Erin Brockovich showed what a difference one smart, angry woman can make in a world that marginalized her. Jen McAdam stepped forward in our time to shut down a diabolical fraud that preys on those most desperate.’ Scott Z Burns, Director (Contagion and The Bourne Ultimatum)

As featured on the hit BBC podcast The Missing Cryptoqueen

Jen McAdam was a victim of the OneCoin global cryptocurrency fraud, which stole an estimated $27 billion from ordinary people around the world. The evil genius of the scam was its target, society’s ‘unbanked,’ not wealthy investors, and it robbed millions of their livelihood and futures. The poor became poorer.

The brutal plundering led by self-styled Cryptoqueen Ruja Ignatova defied all legal and banking barriers bamboozling financial authorities ― until Jen McAdam fought back.

With a £15,000 inheritance from her father, saved from a careful life in a west of Scotland mining town, Jen wanted to invest wisely for her family’s future and was enraptured by the possibilities offered by OneCoin’s promotional material and convincing endorsements from celebrities and financial institutions. They, like all Dr Ruja’s flamboyant promises, were bogus.

Jen McAdam was the first victim brave enough to fight back and despite death threats and an intimidating campaign to shut her down, and through a debilitating illness, strived tirelessly for justice – for herself, her family and friends, and the millions around the world who lost everything. 

She created and continues to lead victims ’support groups and in 2023, as the OneCoin bandits were being punished by international courts, spearheaded a move to get financial compensation for the many whose life hopes were cruelly crushed by the Cryptoqueen.

This is a true David-and-Goliath story. It shows us the power we can have as individuals, even when things seem hopeless.
