I put coinhive on one of my websites to test it out, but some browsers are starting to flag it, causing trust issues with users.
It didn't make very much, like $20 over the course of a month, and this is on a website with thousands of daily visitors.
I think the only way it could make decent money is if you have a ton of traffic, and I am talking hundreds of thousands a visitors per day.
Else its not worth it.
Something is not right
when you have a ton of traffic basically you have a decent and good site
As you've observed not only the users browsers flagged those mining scripts embedded but also with AV's
as a result, your site visitors would probably decreased compromising web traffic into small profits on web mining
If the site is a selling web, that is a bad in business
