I steer clear of ALL cloud mining been there and bit before the "company" had been running for a couple of years had rave reviews the lot and one day the site closed and went offline along with 1000s of peoples bitcoins.

Basically was just a ponzi scam using the received bitcoin to make weekly payouts to the users giving the impression they was mining but really no mining was going on just re distributing received funds got to the point where payments were "delayed" while trying to recruit more users and eventually shut shop.

The users that joined early got there money back but the late comers will have lost everything.
