Free cloud mining site

I have multiple signup of mining site that I see in Ads, Video blogger and search some. I stable to this site because, 'Yes, because it's free. Who would not to smile when you read or see that this free site could gain an income that you have to do nothing. I saw people review some site that pay them and I'm jealous to them. I experience that we have same site he or she can withdraw but me can't. Why is that? Maybe because they invested and have referral. Me I don't invest and don't have any referrals.

It's great site for beginners like that can gain potential income in a easy way.
