The interest rate is indeed very suspicious. But would a legally operating exchange do such a thing ?! If that's true, then these people would go 100% to prison in Russia.
I will wait for yahoo's decision just because it is unbelievable to me that they could do something so insolent.
Since when Yobit is operating leagally? They don't things like license which would make them fully leagally operating exchange and nobody knows who owns Yobit and etc. And IIRC, Yobit was previously even banned in Russia
