It is sad that you still haven't yet recovered your funds until now, but what is more sad is that you haven't yet moved on until now. If you were not able to get it back in 2017 and in 2018 and then in 2019 and 2020, there is almost no reason at all why you would get it back in 2021. That's YoBit you are dealing with. It's a scam.

But I am curious, does this involve a big amount of money? What have you done to try recover your funds these past few years? I'm afraid people here might have nothing to help you in this case.
