Why did you choose to deposit 1000 ETH on yobit?
I have tried every possible support channel with Yobit. Only running into scamming-sounding supporter. My ticket on yobit.net never get replied.
Since it is a lot of money, I recommend that you hire a good lawyer and report your case to the police so that the police can make the necessary investigations to find the yobit owner and his headquarters for him to answer in court and the court will oblige yobit to return the1000 ETH to you, I am not a lawyer but I believe you will have to explain the provenance of these 1000 ETH, so I suggest you have the proofs of the provenance of these 1000 ETH.
