Is it closed now?
Their facebook page has disappeared, and I haven't been able to get any withdrawal after 10th Jan.

Dear Raj,
It seems Etherminers turns into scam more sooner than we thought. But, you don't lose your hope because this kind of sites sometime can back in track and again keep on paying, however, most of time just stops paying forever. That is the reason why we always list these kind of sites within our "Not Recommended" list.
