Stupid question, does anyone do this on purpose? (i.e. With the consent of the client side). In a way it seems like a good way to make income for content (say a blog post) rather than all the ad profiling nonsense that goes on now.

I noticed that the nazi/terror/nationalistic organisation Nordic Resistance Movement uses https://coinhive.com, since they probably can't use ads. Coinhive apparently takes a 30% cut, and on my 2014 15" MBP I get a hashrate of around 50 / second. Some napkin math:

  ((50 hashes / s * 100000 vistors * 5 minutes)) / average hashes per block[0]) * block reward [1] * 0.7 ≈ 70 USD cents.
  [0]: 54272216853
  [1]: 4.11 XMR, 1 XMR ≈ 90 USD

So for spinning the fans for 10 0000 people for 5 minutes while they reads your blog post, you get 0.7 USD.

Thanks! That is strangely fascinating. So I am guessing your average laptop runs at about 20 watts so 20 x 10000 x 5/60 = 16.67kwh So depending on where you live you might pay 0.3$/kwh so 70 cents for about 5 dollars worth of electricity. So only makes sense if you can keep a lot of people on your page for a very long time...

I would be surprised if a javascript cryptominer was productive enough to even be worth the effort.

I'm completely naive about such things, what sort of productivity is it in say $/hr/core
