The second domain name you mention is a scam of course (
see here). If it was from Cryptomixer.io it would have been announced somewhere, and at least added to the original post. Anything else found on the web should not be trusted.
The person behind the phishing site also owns the domain coinswap.cz
Thank you for explaining about the site.
even I was very surprised after visiting your link, it turns out that you have a project which includes a long list of phishing/scam domains. that's so cool friend.
