On 21 December 2021, following an FCA application, a UK Court made a special administration order to the FCA-regulated e-Money Institution (EMI) Viola Money (Europe) Limited, established by Christopher Hamilton via the Maltese Viola Group Holdings Limited. Law enforcement investigators see Hamilton as one of the key people in the OneCoin crypto fraud scheme, who allegedly laundered more than $100 million for crypto queen Ruja Ignatova. The U.S. has requested his extradition.
