What I always wonder about those kind of projects is why you never find any specs about the software they use. Not only that it is closed source (what I expect) but they don't give any information about how big it is and what you would need to run it. You have no control about what is executed on your PC (possibly as root?). In my eyes it completely destroys the integrity and trustworthy of any computer it is installed on.

I also wonder how they calculate the money you get just for having certain hardware. It says a 6 core 3.2Ghz CPU pays out $28/month but what if I have an average of 70% CPU usage the whole time (unrealistic, but still what if)? Do they pay me still $28 even though they only get 30% of what they could get or do they reduce the payment or even worse does the software just take the whole CPU for it self and make the rest of the computer unusable?

I've seen some similar projects (don't remember the names) but none of those actually answered only one of these questions.

I don't think they pay you just based on hardware specs. It's a factor of time that you allow the program to run for, and how much usage of the hardware it gets. Their estimates are probably some middle ground of 50% of the day and 70% usage or something, with the $28+ meaning you could get more for longer/higher usage. It's unlikely that the average working person, with only a couple hours in the evening with their machines turned on (and also actively using them), would earn nearly that amount for the limited time. Especially gamers, where they have significantly better hardware than the average home pc but likely have much higher usage of the hardware. I doubt my pc with a gtx 970 would earn close to the $32 it mentions as I only use it for a couple hours an evening, and in that time the card is working really hard playing modern games in 4k resolution.
