Dude, why did you send around $ 70 000 to unknown and scammy exchange which was made by Russian scammers ? Now there is no way to return your money back. The only thing you can do is to fill the form and inform department "K" of Russian police which is dealing with internet crimes.  https://xn--b1aew.xn--p1ai/mvd/structure1/Upravlenija/Upravlenie_K_MVD_Rossii  (You have to provide all details including the website address of scammers and all other necessary information.) Good luck. I already reported their profiles to the bitcointalk administrations with a request of permanent ban, due to scamming people.
