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
If you want to generate income for your website then using secret miners like Coinhive just isn't gonna do it. They're flagged because people have been abusing their use. The only way to do it is to use something that's totally transaparent with your users, otherwise you're shooting yourself in the foot.
