i noticed many coins there are in "maintenance" mode, for a while. They recently announced maintenance, but even if the timeframe is over, many coins are basically on hold there. I hope its not same issue like with the other big exchange that tried to cover a hacking incident under "maintenance" recently.
Also its possible since the entire market is going strange ways, that they locked some. VOT doesn't seem to be locked , but not so long ago when i traded vot there it went very smooth, so what is goin on now is not how TS used to work.
