Advertisements eat resources while loading and once that is done they do not keep refreshing themselves to eat more resources. Cryptominers have a very different behavior. They reserve a % of system resources to keep running in the background as long as the site is kept open even in a dormant tab. So if your system is at 10% load usually, cryptominers could keep them at 20-30%+ load all the time they are in memory without the user knowing it nor approving it. Unlike advertisements we do not see them running or loaded in front of our eyes either. Don't you think this is very invasive?

Advertisements eat resources while loading and once that is done they do not keep refreshing themselves to eat more resources. That is no longer true - on several sites (eg. Ars Technica), ads are loaded and refreshed after a short period. I haven't yet seen anything close to as resource-intensive as a cryptominer yet... in terms of CPU. In terms of bandwidth, I would not be surprised if most ads consume more than cryptominers.

  That is no longer true - on several sites (eg. Ars Technica), ads are loaded and refreshed after a short period. Auto-refresh ads still do most of the work on the ad servers and very small amount of resources are eaten on the user side in the browser. This too is done with a predefined logic which are user-action based or event-based. Time-based auto-refresh ads are only seen on bigger sites which usually have very high average session times. So regular news and clickbaity sites won't necessarily have those. Auto-refresh ads are only served by bigger ad networks which server bigger sites, Google Adsense do not allow auto-refresh ads. Google Ad Exchange does but that network is for bigger sites. This weeds out all the potential scammy/spammy sites which go for exploiting user resources like cryptominers do.
