Cloud mining sites are really great and easy scams if you want to scam people who are new in this type of thing. People want fast and big returns and cloud mining scams offer such great profits.Too bad people rarely realise if something is too good to be true, it is not true at all. There are a lot of cloud mining scams and most of them were very profitable for scammmers. A shitty website and a couple of people promoting that site for their own gain. And thats it. Scams such as crypterra which was not even a good scam that had a site that only had stock images got away with millions of dollars.
