You would think a site this big and nice would not have manual withdrawals but it does! Gotta wait up to 24 hours but Im sure it wont take that long. Ive only been waiting for around 3.5 hours so far. :/
For security reasons mintdice process the withdrawals manually which has the positive side also other than the waiting time.But from my experience I never waited more than 30 minutes for my withdrawal to get processed.So its not happens always sometimes there will be a delay.
