Yeah, I was wondering if it was scam or some kind of ponzi or not. But based on the details(such as the refferal bonus = 30%) seems quite large than the normal one, which should only be 10%. Now, I want to invest but I am afraid that the first indication is holding me back fearing that it will run away in no time. So, Please share your testimonies or proof of payments so that we can know if this free mining site is legit or not.
what 30% are you talking about? "Commission is 3000 satoshi from every referral, after referral upgrade warehouse to 15 level" this is a quote from the site. +you get 5000 when your referral signs up. That's all you can get from him/her. It is not much. Most people say that they didn't get their payments, so the way payments arrive or don't arrive should be a random one. If one's lucky enough he/she gets paid 
That's only my opinion of course
