If people would bother to do some actual research they would quickly find out that there are a few ASIC manufacturers providing cloud mining services. Instead, most people waste their money by throwing it at obvious ponzis that refuse to provide any evidence of legitimacy despite. And that's after being warned my multiple people not to do so. And then they start crying when they get ripped off.

It's as simple as this. If a company/service/whatever refuses to provide any evidence of legitimacy, don't give them your money.

Also, compared to AMHash (ASICMiner) and Hashnest (Bitmain), CEX.IO was insanely overpriced and less legitimate.
