Hi, I don’t know how I can get the money or I don’t understand
Depends, if you are a normal user just activate the rewards and configure the number of ads seen peer hour. You would see ads like notifications, you can click on them and earn BAT.
If you are a content creator of some kind, searh for brave creators and signup as a verified brave creator. Then add your personal site, youtube channel, Twitter account, etc, etc, to let others tip your content.
