How to receive BAT and convert to cash

In my understanding so far, we can earn BAT rewards and share with other content creators, but there is no way to convert that to cash that you cannot withdraw and use for yourself. Someone teach me otherwise if you have found a way.

I feel like we are being played here. And there are ads that are coming through the brave browser right now even where I have not allowed the site. Which means brave could be receiving some payment for that.

AUTO CONTRIBUTION option can I enable or disable?
