Yobit has been down for ~ year.
I send numerous emails and bombarded their troll box in every language for weeks.
They will take it out of maintenance , but then will place it back in maintenance almost immediately.
I finally gave up on them.
Which if you look everytime I show the exchange status it always says:
Exchange Status
Yobit Do not use Yobit
The only suggestion I have left , is to sue them when the value of your coins is high enough to make it worthwhile.
just sell your Zeits on yobit, their BTCwallet is almost always online. then you can convert the btc to lite or doge on the other exchanges and buy them back profitably
+1, and then refer to kiklo's statement in red above: DO NOT USE YOBIT ever again!
