We've still got BAT enabled on PortableApps.com with the standard custom Brave browser header and donation ask you setup via their program. We got 31.35 BAT (about $8.08) for around 2.7 million page views in the last month. We also got a single 0.95 BAT (about 24 cent) donation. It seems that - right now at least - the only way a site will make enough money to be worth it is via Brave referrals (advertising Brave to your users to get them to switch).
