I remember when cloud hashing just started, they were promising that you would make X amount of bitcoin with X amount if investment within one year.. There was no way they could meet those numbers, it was false advertising. I emailed them a few times to educate them on difficulty, etc. they just blew me off..

You will never get your ROI on any legit cloud mining service.. Most are ponzi schemes as Gavin said. I dont think Cloudhashing is, but PB is 100 percent scam...

Its better to invest in bitcoin and hold. I would have bee a millionaire many times over had I took my own advice.. but no, i had to get into mining. Should have stayed with the fpga, that was actually very profitable. but not since the asic race took off. Buy and hold.
