These are Cloud Mining companies, right? I read your Whitepapers, but since I am not someone with a lot of technical knowledge then I can not say if it is possible they can provide profits for the investors, however I read this:

Genesis Mining Voids All Unprofitable Contracts, Deploys Radiant Tech Amid Bitcoin Decline

weeks ago, hashflare did the same thing and that means that this cloud mining business may not be more profitable for its owners, because for the investor it is much clearer that the best option will be to buy bitcoin and hold for years instead of waste time and money using cloud mining. So here it raises some technical questions that I could not explain better.

why several miners are not complaining and only the cloud mining are complaining of not having profits because of the fall in prices?

Why does every cloud mining site only show the equipment and does not show the outside of where the equipment is? Is it because this mining activity is illegal in some countries? I have not yet seen a cloud mining company show any license
