I beg to differ. I've tried Coinhive's miner, it used all of processor's threads and making my browser unresponsive, couldn't even move mouse pointer or close the browser. Mining coins on a browser is bad for everybody involved, especially for the users.

>A coin being mined is controlled, handled entirely by first party, provides no incentive for tracking, etc.

Yeah, also a haven for hackers and malicious actors...

EDIT: I guess you weren't aware. CoinHive doesn't track the users who sign up for the service. It doesn't collect any information except email address. So malicious actors can easily sign up for the service and deliver the javascript through an XSS vulnerability for example. I thought that's what you meant by "no incentive for tracking".

In what way? I consider this a security win. Instead of a third party delivering unknown, unscreened content (ads), I get a mining script directly from the site that I'm visiting.

That’s all true.
