I am personally convinced that it is. I've discussed cryptotab with some people, and mostly they show concerns regarding the pyramid structure of extra rewards which I have no problems with. Also, they show payments journal publicly. Also, you can set the mining speed so that your CPU doesn't overwork.
I'm genuinely curious so please forgive me if this is a stupid question: what would be the cons if we'd run it on primary computers? Privacy issues?
