How long does it take for Cryptsy to withdraw BTC???
13 hours and it's pending...
Can I cancel it?
Normally not that long, I withdrew last night and it was actually pretty fast. Did you confirm the transaction through the email?
Yes, I did.
I withdrew it to Mintpal should it be a problem?
If it's saying pending in Cryptsy you won't have a TrxID which means it won't have left Cryptsy, might be worth dropping them a support ticket. If you do have a TrxID, go to Blockchain and search for it.
