What steps you need to take to earn as much as possible BAT from your Brave browser ad clicking experience:

1) turn on a VPN to USA IP-address as the vast majority of ads are offered to US market (with a European IP-address you hardly get any ad).

You can use free VPN apps, like the one in the example.

Choose US address and hit connect button.

2) next turn the amount of ads that are shown per hour to maxim of 5 in the Ads Settings panel of the Brave browser: Ads --> View details

Now set the amount of ads to 5 per hour and you are ready!
