https://bitcointalk.org/index.php?topic=5038479.0If i were you, i would withdraw my money and avoid using that exchange. It's a time bomb waiting to explode.
the reputation of that exchange is really not clean.
logfiles is right, better withdraw all your funds from that exchange because it is only a matter of time when will they declare hacking incident or bankruptcy. but storing funds in any exchange is really not advisable. but this specific exchange, is really not to be trusted based on previous shady behaviours towards its traders.
as
sunsilk has suggested, contact the bitforex support directly. i do that also whenever my withdrawal is delayed and beyond the normal waiting time. and you will know what is their reasoning from their end.
