This is a good feature from brave browser community. I have used it for more than 1 year. But one can earn very less amount of bat token from ads viewing daily. But something is better than nothing. And also bat has a huge potential on the crypto market.
If you are old brave users well thats worth it. But if you are new that want to earn from ads you need to first buy the tokens to be able to very the wallet you need minimum 25 bat tokens to be able to verify it and to recieve rewards for having an ads.
No idea why they make this but its not good for those new to this program and have difficulty to understand block chain .
