I just pointed out to the fact that hashnest offered a rate lower than cloudmining.website. Shutting down due unprofitability may depend on various other factors as well. Cex.io paused mining for public, while their rate was far higher than the competition.
So I point out that your claim to that particular hashnest service being cheaper is irrelevant because it had to shut down several months ago as it was unsustainable, at a point when difficulty was much lower than it is now, and you then cite cex.io shutting down likewise and that it's prices were higher?
I'm not sure how you think you have rebutted my point, which is that cm.w is significantly cheaper than that needed for a legitimate operation to be viable.
The difficulty is constantly increasing ,and mining rigs are out of date quickly. The profitability for Cloud mining companies just depends on the selling price of hash power. They cannot keep the same price forever otherwise they will soon collapse. It is just a matter of time.
