What can be done if anything through legal avenues for people to get their stolen money back?
There are already large companies in the world that are fighting against online fraud, hacking, theft of funds, etc.
https://www.group-ib.ru/If you have been cheated for a large amount and you have the means to hire professionals, then you can try to contact such companies.
But their services are very expensive 50-100 thousand dollars and more.
They work with the police of many countries, and after the fraudsters are found, their data will be transferred to the police.
That's the thing though, if you have been scam just a couple of thousands of dollars then it doesn't make sense to spend $50-$100 thousand just to chase those criminals. However, perhaps these victims can group themselves together to strengthen the case and maybe they can file it against those fighting online frauds.
I'm not really sure though if this has precedence already. As far as I know, it's either the US DOJ or SEC are filing criminal complaints and chasing this fraudulent projects in crypto space
I watched interviews with these guys. Interpol and other interstate structures are working very slowly. It takes a very long time to request and exchange information.
These companies can quickly conduct investigations and transfer data to the police of different countries.
Cybercriminals are now getting huge prison sentences because they are found quickly, because there are many ways to find hackers.
