Sad to see the site turn up as a scam. I was in contact with the support about buying a plan, but haven't heard back after 5th.
They probably shut down after the price drop. (either the whole thing was a scam and they sold their coins, or mining is no longer profitable)
It's pretty sad to come to thic conclusion but this doesn't look like anything else other than a scam. A short lived one too. On the positive side though, cara ran the campaign honestly and participants received the BTC they earned.
