I will probably give it a try tonight. Have already downloaded the Brave browser.
You can earn BATs up to $10 a month. Varies from month to month and your personal browsing activity. But you need to know - in order to prevent any dissapointments - you can not withdraw those earned BATs yet. You can only donate them to websites, youtubers and twitcher at the moment. Withdrawal feature however is in development.
In the meanwhile (my post you've quoted is from May 2019) there was implemented a withdrawal function. You can now withdraw your BATs to Uphold wallet. However a KYC is needed to open an Uphold account. According to the website, Brave is working for more withdrawal options which do not need any KYC.
