I think that every third thread is related to BAT token, they are really doing a nice job and I hope rewards are going to worth it. But as far as I know even by showing in every advertising, you cannot really earn a good amount of BAT tokens.
BAT attracts many people as you can earn it simply looking through ads on YouTube and some other sites through the Brave browser. It seems to be a very curious proposition. So far, developers do not have a specific system for evaluating the cost of advertising, but they promise to complete it. According to them, the cost of advertising will be estimated depending on the duration of the video and the number of pixels in comparison with the content of the site.
