I can't say c-cex.com is a scam site or not. I use that exchange but not for trading. No, you must have a question why I use it if I don't trade. I have some habits for a long time. I do regi some site to see what have in there. However, After signing up on the c-cex I didn't like all of their systems. So I didn't put any money on there. But I got some coins from outside that's why sometimes I use it.
If you never deposit, trade, and withdraw then you really never use the site. And the exchange has too many red flags, based on google/internet, and in this forum so it's a no,no to use them.
Or it could be that you maybe click some phishing site, I wish not.
Well, it's hopeless if that was really happened.
