I confirm that this is not a scam. I received both of my payouts very promptly and all of the site worked for me. Also I could daily withdraw my profits with no fees. I do have a little suspicion in me that this will eventually crash, but think of it this way. Trading a lot of money will make it a bit less volatile but the profits you make will be less than in short term investments. If cryptcominer can get more users funds, they can profit more and make it easier to pay back the 3% or whatever. They can make probably 5% or more per day if they work hard and are smart.
