I really like their brave browser and in the last few weeks it has become my new main browser. It works great and is simplistic in it's looks and functionality. The Ad-Block function works also really great and does not have to hide itself from other adblockers like the adblock+ addon of firefox for example. The ads which are shown to me are pretty much the 5 same ads over and over at the moment but i think with more adoption there will be also more customers coming in to buy ad-space on the brave browser. The income you can make as a user is negligible though with around 5$ per month if you use the browser regularly.
