I'd suggest finding out, in the real world, if it is ads or mining that gets you the greater income. Then, you optimize for that. In either case, when you're having them doing the mining, I'd recommend full disclosure AND I'd recommend some explanatory text that goes into the details of what you're doing and why. Something like, "Click here to learn more about mining." That should do the trick. I'd just put said link below the quick blurb/switch/invite to use mining. If mining generates more income, then you may wish to offer some sort of in-game bonus for those who enable it. You'll have to figure out some way to ensure they really have it enabled, of course. Giving them a reward may entice more users to choose to do mining. Another post mentioned that this would be a battery killer. You responded that you'd only enable it for certain devices/browsers. If you want, you could probably enable it (as a choice) for all devices and browsers BUT I'd absolutely ensure that you made it very clear that doing so would mean a rapid depletion of stored energy on battery powered devices. The reason I'd suggest you do allow it is because many people only use mobile devices and, in some cases, will operate them while they are plugged in. For example, I'm typing this on a tablet that is plugged into an outlet. If mining makes you income, I'd be inclined to want to do mining for you - even while on a mobile device. It'd be even more tempting if there were an in-game reward for it. Sort of related: That might make an interesting funding option. Free games but mandatory mining on behalf of the creator. Obviously, full disclosure is required if one is concerned with ethics. Inside this idea, they might be able to get rewards directly related to how much they mine on the creator's behalf.
