Ad blocker use is on the rise. While using CPU of users to mine crypto might be a good alternative, why not try and support artists?
The concept would be to replace ads with art either purchasable or from museum collections.
Auctions as usual or affiliate would produce income. However, a free layer would be presented if no bids or affiliate is found.
Browser Plugin VS Publisher Network
If you monetize the ads and focus on user acquisition via a browser plugin, you may get lawsuits from publishers as you are stealing their income. It does open up data selling.
On the other hand, recruiting publishers may be a hassle. It is a pretty simple sell if you brand it as a way to convince ad blockers to white list your site. It may be potentially viable to have ad blocker extension enable your ads by default.
