A little over 800 BAT this year: https://i.imgur.com/p7o6QKT.png
That's ~400 dollars at current BAT prices ($0.49) or ~1200 dollars at the price BAT was ~1 month ago ($1.50).
It's not a lot, BAT value isn't very stable and I'd make more money with Google Adsense, but this comes from users that block ads anyway. 400 is better than 0.
