I almost got about 1 BAT this month after more than 100 hours of usage. I am not sure if it will get credited to me though (even if I just contribute it to my favorite sites and not withdraw it to Uphold because of the privacy-intrusive KYC), because the tokens suddenly disappear from my local Brave browser's wallet without explanation.

Regarding if 25 BAT is good, it is relatively very good compared to mine.
