Cloudhashing has been a huge disappointment on several fronts:
1) Clear violation to contract in fulfilling promised GHs increases.
2) Failure to deliver on scheduled RRP (reinvestment of BTC into new GHs) dates repeatedly
3) It seems they are just as susceptible to the same hardware backlogs as any other user despite their claims of priority with the OEMs
4) Ridiculously poor block returns, which they repeatedly claim is normal, but from best I can tell relates to their small total THs
5) If it's not that, it's outright theft or incompetence (I'm giving them the benefit of the doubt)
6) Contacting customer service gets one nowhere - they just blame their suppliers, and make no attempt to compensate for my missing profits
7) Overall it's been a waste of BTC so far
They have lost all trust and reputation in my mind, but I get it, they're just trying to make a business in a virginal industry... if I didn't understand the risks I would be making a much bigger stink. But either way I would stay away from them - I could have bought BTC and been much farther ahead by now. They have failed to deliver and don't seem to care.
