As far as I am aware, Yobit will not swap old PAC to $PAC. So they will just vanish after certain date.
I suppose we need to sell PAC at yobit since they disabled cashout.
I've tried an hour ago to cashout my PAC coins to redemption wallet so that to exchange them for $PAC but not success.
At first the wallet shows OK status and online but upon requesting withdrawal the system says that withdrawals are disabled.
