I couldn't access the site and trying to search it from google about this term "Coinhouse.eu" but the result is "https://conhouse.eu/" on the top of the google.

Let me ask what is your issue about this site?

Edit: I found this site from here https://web.archive.org/web/20180628140351/https://coinhouse.eu/
It looks like it is not a well-known exchange site and I couldn't access the live version of the website.

I suggest you don't use untrusted exchange or not well-known sites because there is a huge possibility that you can be scammed.
