I don't know what happened to this exchange nowadays, I don't C-Cex can steal away trader's balances as there is no such evident but the situation they have created nowadays is condemner. Personally, my 4 Altcoins--ZZC, SIBCOIN, BURST and EVR are stuck since long in the form of deposit/withdraw, yet they are unable to resolve a single of them. I believe that the problem is with their Support team, they can't handle queries in time and efficiently, I don't know how to contact them as every channel is silent nowadays, however, we can just request to clear these issues sooner as possible because C-cex is losing their credibility in Crypto market gradually.
Sell and withdraw with a working coin, like Ltc or ETC or BBP. Always do a micro transaction first. I had a bunch of Burst on Ccex when I did a small withdraw I saw it did not work. Seems alot of their coins are out of date chains/wallets. I don't know if they ever plan to do a site update or anything. They are pretty quiet about whats going on, which is kinda scary. Before when they where admitting to issues I wasn't worried, but now I am.
I think if they just shut things down for a bit and took a week to update coins one at a time in limited service mode or something it would do alot of good. I mean if they had some communication like a limited service mode with a *daily* tweet, like -Begun Syncing XYZ coin wallet today Or - Installed new XYZ wallet or whatever. I'd be happy if they even gave an estimate as to how long it will take to replace the doge and ltc. Like 1 year or 2?
