I have installed the browser more than 30 days ago, in first days of use the earnings were very quick, i had 8 ads and got 4 bats, now i have watched 27ads not even close to 3 bats although the most of the ads i see are the same as the ones i got first days of use.
That’s seems very strange for me, I used the Brave browser for more than 30 days as well and I never got so much bats. The later one seems more likely as 4 Bats are almost 1 Dollar … and you can have up to 5 ads an hour … so to earn 1 Dollar every 2 hour seems a bit heavy to me. Perhaps it was a bug back then?
Another possible explanation for that could also be that you get paid a certain value (measured in dollar) in bats. As you now bat is a crypto currency, so what one bat might not have the same value today as it has tomorrow. So it would be interesting to know, if you earn for every bat say 0.02$ in Bat or 0.08 Bat . It seems quite unlikely though that this is the reason in this case as the value of Bat has not changed that much in 30 days as far as I know.
