I take it you're looking for an exchange where you can trade altcoins like on Bleutrade? Personally, I've always liked Bittrex, I've tried a number of exchanges but always end up going back to Bittrex. I've never had any problems there, support is good and deposits/withdrawals are processed reasonably fast. Poloniex is also very good.
Cex.io is aso another very good exchange / trading platform, I have used it for so many times and I am very happy about it. But the main issue with cex.io is that it will require some form of personal information for verification before any transaction could be carried out by you.
I dont think that is something new for Cex.io or any of the exchanges most of them have a Know your Customer policy in place for years if you dont provide documents they will not allow you to create an account.
