Well I was lucky to get all my coins off C-cex the other day but it was very frustrating at times because of all the failed to send coins. I did them in small withdrawals of 20 to 50 coins at a time and it worked most of the time. Let's get MOIN on Bittrex and Poloniex! Tweet to them once or twice a week like I am doing and hopefully soon they will listen to the MOIN community.
