You are absolutely right, it is a scam site that uses CEX.IO lookalike interface.
Please be careful with this and similar fake sites. We ask you to be very cautious with sending the funds to sources you are not confident about.
Also, be kindly notified that CEX.IO is in no way related to 'Bitcomion'.

Thanks for your quick response. I hope you take action against the scammers. In the future, scammers should not use your template to mislead people. If I find more websites like this, of course I will post on Bitcointalk. Keep eye on Scam accusations board for more fake website like this.
