I do think that the Indian government should make some exception to the legislation in order to refund the victims, though. Because after all, even though getting scammed is somewhat their fault, a ponzi scheme at the end is illegal and its victims should be reimbursed.
This should be the action that the Indian gov't would do. But I don't think that they will do it, returning "illegal" money on their perspective won't work. They have all the rights to do with the seized money like what happened to the funds that were seized during the Silk Road days.
Well, great! Here is a prime example of what the lack of regulation can lead to.
Although in this case, it seems to me that the victims themselves need to take the initiative. To demand the return of funds not stolen from them, but to demand the return of information stolen from them. After all, do not forget that blockchain is a database, i.e. information.
The question, Is the Indian gov't will cooperate?
