I do not recommend to do cloud mining because all in all, you will not making a profit with the site especially today, there is too many cloud mining site that claims they are legit one but the truth is they will run away after a few months later. it still better to buy a hardware and mining in our home but it depends on how much electricity fee that we should pay. maybe in a few years ago, cloud mining can give profit to you, but now, I don't think that you can get ROI in the short time.
I gave an example in the article how you can earn on cloud mining. The problem was so simple that I declare that cloud mining is not profitable)
Because of the simple users who are trying to replace the order at any cost go to a very low price.
But if you have a powerful farm - this method will work for sure.
