I agree with you that cryptoex.cc has some similarities to coinmarket.io but some users in this thread got paid out recently. So this doesn't match the pattern of a scammer. As I've read, that someone said that the same engine is used. How can someone know this? IIt could be a design ripoff as well.

I wouldn't recomment coinmarket.io to anyone anymore because of the problems they are facing right now. But the witch hunt against coinmarket.io seems as it has gotten way out of control (death threads, seriously?).
I've only got noble stored on this exchange as it went down, so a block explorer would be helpful to check, if the balance still is on the site. But I am not convinced of a scammer just because of two blockchain links to empty wallets (which got cleared in a time span of more than half a month).
