Last year I used Tinder to investigate romance scammers tugging at the purse strings of besotted would-be partners. After publishing the findings, a Hong Kong woman offered to help victims reclaim lost monies. What happened next was sad and exhausting.
OneCoin
OneCoin was a proven ponzi scheme masterminded by Bulgaria-based offshore companies OneCoin Ltd (registered in Dubai) and OneLife Network Ltd, and promoted as a cryptocurrency despite having no blockchain and using a falsified ledger.
The figurehead of the scam, convicted fraudster Ruja Ignatova, is still at large, on the run and wanted by international authorities. In her absence, she was charged U.S. authorities with wire fraud, securities fraud and money laundering.
