I finally managed to withdraw my last funds from poloniex, which I have been doing for the past two months. A large portion of my funds were locked in long running lending contracts, so I had to wait for those... Actually all withdrawals have been mostly problem free, except for a small ETH withdrawal that took several days to clear, but it did eventually. Regardless, feels good not to have any funds on any exchange for peace of mind, especially taking into account the publicity around poloniex lately.
