I would prefer to invest to a legitimate company that is located in one of the countries of the European Union. There, legislation looks more closely at such companies.
White Paper says they are licensed and registered in Malta. "The AMANPURI Exchange is a licensed DLT exchange based in the Republic of Malta that offers first-class VFA and VFA/FIAT exchange and payment solutions."
All licenses and certificates should be visible to everyone on official sites. Where can I verify the availability of this license?
