I use Brave too. Brave earns because an advertiser pays for adspace. Same as Google display ads. These ads are shown to the people who turned on Brave Rewards (99%). A share goes to the person who watched the ad, another share goes to Brave itself. With these earned rewards (in BAT) a Brave user can now select a couple of favorite authors (Reggaesteem.io for example) to tip every month or one a 1 time basis. It is not the author (you or me) that gets the Bat, but the website. So you can ad reggaesteem as a verified publisher, and the YouTube channel too. Now you earn Bat on all the Brave users who blocked ads on your site anyway. I know from experience its not quite as much as with regular ads. But something is better than nothing and it picks up in time
