London-based cryptocurrency lender Nexo has closed two of its subsidiaries in the UK as part of a company-wide restructuring. The closures come as Nexo faces an investigation in Bulgaria over allegations of involvement in an organised crime scheme. In January, Bulgarian authorities raided Nexo's offices in Sofia and charged four people working at the company with forming an organised crime group and committing money laundering, unlicensed banking activities, and tax and computer crimes. Nexo has also faced legal disputes in the US, including a $22.5m penalty from the Securities and Exchange Commission for failing to register its retail lending product.
