I am skeptical of Brave, because their business model seems hand-wavy and their crypto shit seems skeezy. But right now, I can't think of anything offering better ROI for ad/tracker blocking.
If you are going to tell your parents "just set up pi-hole on a cheap raspi, or spin up an LXC or Docker container to run it on your LAN, then use it for DNS" then you definitely have different parents than I do.
But pretty much anybody who uses a computer can install and run Brave.
Micropayments in lieu of ads has been a dream of many for a long time. Brave is doing that, and the crypto part seems like a rare appropriate use case.
(Admittedly, I only use Brave for a small subset of websites.)
The coin works such that Brave buys BAT with a percentage of their normal money ad revenue, distribute it to users who can then use that to tip content creators with Brave's tipping service. Content creators can then sell BAT for real money, and there's always someone buying, namely Brave. It's pretty much the least scammy crypto coin I've come across.
But when I tried it, the ads Brave served were much worse than banner ads in a web page — they were super-intrusive system notifications, with ad payloads in them. I can't imagine any significant number of users ever using Brave with those ads enabled.
Likewise, I have never seen a website that is willing to accept my BAT crypto, other than the one posted in this thread.
Perhaps the second point (micropayments to authors) is not critical to their model, though.
