“There are authorities at one of Nexo’s offices in Bulgaria which is, as you know the most corrupt country in the EU,” a Nexo spokesperson said in an email to CoinDesk. “They are making AML and tax-related inquiries about a Bulgarian entity of the group that is not customer facing, but only has back office functions – payroll, customer support, compliance. We are one of the most stringent entities with regards to KYC/AML.”
