Although i saw this red warning i changed my deposit adress, and i sent the last changed adress.
So do i have to now? i'm severely worried.
Yes you have to be worried lol.
Although Yobit supports sucks, try to wait for
"little" longer for their response. Your patience will be test here lol. Sometimes it will automatically be reflected but we don't know how long it will be. I just can't imagined why you choose Yobit as there are other trading platforms that listed Dogecoin. Since you are expecting some answers with them then your option only is to wait as no one can help you here even the Yobit's bitcointalk account. Try to hunt for Yobit admins at their trollbox (e.g dominikherzog). He is currently online while Im typing this.
