How brave rewards work?

Hello , recently I activate the option of brave rewards but, how it works I gained 20 BATS but how can I have this in cash it is possible? It’s necessary to have a web page to claim this? The BAT only is for support creators?
Thanks

That’s free grants. To help users try the Brave Rewards system and use it to support creators/publishers.

You’ll not be able to withdrawal BAT from free grants. If not used within 90 days, it’ll be sent back to User Growth Pool.

No, you can use Brave Rewards and opt-in to Brave Ads and earn BAT as a user without being a verified creators. BAT that you earn from Brave Ads can be used to support creators or if you want, you can withdraw it.
