I think, Yobit going to SKAM.

I've got the same story: At 06.01.2017 I sended to the Yobit deposit 50000 RUR from the Advanced Cash. Transaction number 2fea710e-5e41-4e4a-95d9-978635f31447. But money still not in deposit. Support doesn't answer.

There are a lot of peopls with the same story https://www.bestchange.ru/yobit-exchanger.html
