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."
It is very interesting to look at these documents. I think such information should be on the official site.
