> Brave users can fund their wallet, or earn BATs by viewing ads;

This is where the money making happens, and where actual money enters the BAT economy. Those BATs you get for watching ads have to come from somewhere; advertisers effectively pay for the BATs they give you with real money (I'm not positive whether the advertisers literally buy BAT to give you, or if they just pay Brave and Brave conjures them out of the air). My guess is that they'll make money on service fees on money entering or leaving BAT. Maybe a % service charge on advertisers buying BAT, or the same thing but on websites cashing out.

I imagine they'll diversify and might make some income from referral links or other miscellaneous revenue streams, but I would expect the vast bulk of their revenue to relate directly to advertising and BAT.

So, something like advertisers paying them to display their ads?
