So what is the situation now, is there any investigation being done, i did not loose any coins because i never used to keep any coins in any exchange but the manner in which they lost the funds and one man holding the private key is dubious and since there is no regulation and the government is not having any clarity on what to do with it, i do not think there will be any investigation on the subject, if not we would have heard something by now as it is more than a year.
But the above letter says that the private keys were being held by Dr. Amitabh as well as Mr. Mohit. So we never know who might be the actual fraudster here.
Besides that, it's too difficult to crack down such frauds and trace the bitcoins especially when the country doesn't have any regulations.
So I guess nothing is gonna happen in this case.
