The Bitcoin is being used with a zero knowledge proof system so that Brave will not know what websites you visited. I think they are hoping to be different than flattr in that they are a browser and so might have a more comprehensive experience than a website widget. Also, websites will get their ads blocked regardless of whether or not they have signed up for any service with Brave. I suppose the hope is that people feel guilty enough about blocking ads to pay a flat rate to have the sites they visit compensated.
