I tracked this month very carefully the ads i was seeing(none of them was clicked, so that we know is only seen/dismissed).
Ratio is 0.010 BAT per ad.
Some ads give 0.030, some gives 0.001 and so on…
But at the end, you can see the amount of ads and tokens here in image.
If you check you can see 61 ads and 0.67 BaT, i can bet that the next set of ads(maybe 6 ads today), there will be 68 ads, and 0.79BAT. I will keep track and post next change.
Don t know if it s fair or not, since i never got more than 2BAT even if click them almost instantly.
EDIT
Now i got 0.050 for an ad.
Total ads 62 and 0.721 BAT
Which AD gave this?
It seems ChangeX
Edit
For 2 ads 0.050(each 0.025) BAT.
Who?
