Are you sure about that?
I think I bought 1 gh/s a month back just to try the site.
It just seems, that you hate it, because you got a free 100 Gh/s coupon, and to cash it out you have to buy a mining contract.
Obviously, you can't just buy a 1 gh/s and cash out all the earnings.
I am not supporting cloudminr, but it clearly seems you want revenge that you didn't get your payout
