BAT rewards decreased?

I used to receive 0.05 BAT for watching an ad, now it has been decreased to .025… why is that???

Basic economy.
If the price of BAT goes any higher, you will receive 0.020 for an ad.

@cryptomagi it’s never same. Because it’s vary and depends on the ad value itself. But one thing that never change is that user get 70% of the share.
