As long as they are getting investment from people we are in safe hands and once the interest is stopped we have to face many challenges and there is no guarantee whether we are receiving our investment back. So we have to be very careful when dealing with this cloud mining websites.
You perfectly describe the structure of a scheme, which means that people shouldn't be very careful, but completely avoid it. It makes no sense to use something from which you know that it is a scheme, and that it will likely stop paying out at some point in the future. People won't face challenges and losses if they don't mess around with this garbage, how difficult is that to understand?
In the last two days, Hashflare's maintenance fee was larger than the payout, so they have reached a critical point in their business.
And what is that critical point? They will just make you lose out and they are all fine.
People know that cloud mining sites will stop paying at some point, and yet they complain afterwards when everything happens they beforehand know it would happen.

Its always been part of the human nature on being a stubborn one.We do know already the risk but still we do decide to continue or risk it up.
If we can just mind up the possible things or in future that can possibly happen we would able to avoid it on the very first place if we are wise enough but of us do failed up.
Its being mentioned for a hundred times that cloud mining wont really be profitable on longer runs but still people decide to invest and now they are shocked on what happened?
