What's going on with the Yobit XBY wallet? How long has it been in maintenance?
don't buy anything in Yobit, if a wallet breaks in Yobit it takes ages for them to fix it, that's if they ever decide to fix it!
Play it safe, buy on Cryptopia or C-Cex.
I have submitted a ticket on Yobit for fixing their XBY wallet from maintenance, and followed it up with two messages but they have not even bothered replying to me.
I'm going to submit another ticket today.
