scam or not , i wouldnt still invest my money on their platform because they are not really familliar to me and i believe all of us ( even the op of this thread ) are not also familliar with c-cex.com .
Maybe for you (and others) but not for the rest of us, c-cex is one of the longest running exchange and one of the used exchange way back until they become like this and scamming its users, so no one would recommend of using them these days.
