This is bad news, please be patient. In fact, there my friend also said poloniex often troublesome. I have not tried to enter c-cex. Still faithful in bittrex.
i do not know that what is going on to the exchanges, these are really bad new about the exchanges, i want thinking that c-cex may be the best exchanges as i also have recently open an account there for my signature campaign, hope it is not going to declare as scam. it will continue serving people in a good way.
