coinexchange withdraw has been difficult recently. Bitcoin withdraw is severely delayed and I miss my superbitcoin because of that. But they always answer their support and as of now have never failed permanently for me.
Not sure what others' experience.
I think I am going to reduce my bitcoin there.
The Ethereum network is still congested because of CryptoKitties, hence the delay.
Seems like your transaction is completed now.
