jordanjay29 You mean, how much of the user's electricity bill would end up with the site?
Probably not much. Educated guess: the value of any crypto currency gravitates in the long run towards the cheapest electricity price on earth (eg subsidized Chinese coal power) plus depreciation of mining hardware. With Monero cryptojacking, there is no depreciation, however, the hardware is consumer grade and probably a factor 2-5 more inefficient than dedicated mining hardware. Also, the electricity price in most countries is probably a factor 2-5 higher than the Chinese baseline. Summed up, I estimate that only a few percent of the end-user's electricity cost will end up with the site owner (even ignoring the 30% Coinhive fee).
Still, it could be a viable option, as the transaction overhead for regular micropayments are probably comparable.
Personally, I'm not at all a fan of crypto. I think it's a complete waste of the earths resources and a shameful example of man's greed. And of my own, I admit I used to have some ?
