Lie to me is a documentary about lies, hope and greed. When OneCoin was launched as "the bitcoin killer" in 2014, it was promised gold and green forests. Anyone could get rich if they invested. But OneCoin was not a new financial revolution. It wasn't even a cryptocurrency. OneCoin turned out to be the world's biggest crypto scam, and the man who exposed it all was Norwegian Bjorn Bjercke. Yet the fraud continues. How is that possible?
