I try to report to the local authorities without any luck
Just to be clear, you specifically contacted the cybercrime division
[in your country], right?
It can be important to understand how cryptocurrencies are treated in the particular local law system, so it can be properly presented to the local criminal persecution authorities. For example, cryptocurrencies might not be considered as "property" that can be "stolen", but it may still be possible to create a fraud case.
This organization(s) refused to revel this information to me without legal order
Then work on it
[with a lawyer].
- Don't get your hopes up.( Interpol in this case that is if they will be interested)
They'll ignore such reports unless local authorities or the police submits them:
If you need help [INTERPOL]The local authorities will contact Interpol if they figure out it's a cross-border situation. Success will still largely depend on the work of the local authorities both where the victim lives and where the money went. It can be helpful to understand how to escalate the case to the next higher authority. Still, there is often little chance to recover much of the lost money.
