> 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?

Yes, see https://brave.com/brave-ads/. We take flat 30% of gross paid to us.

They created 1.5B BAT

"- Once a month, they will split the BATs I earned accordingly by each website I visited(is there proof this happens?);"

Right now if a website is not Brave verified, that donation intent just sits in local storage and re-attempts itself for some period of time.

Brave makes money by being the ad regulator and distributor. If a publisher spends X on ad spend, users get 0.7x distributed back and Brave keeps the delta.

Advertisers can pay in BAT or just send Brave fiat and they'll purchase BAT on the open market as shown here: https://brave.com/transparency/.

Thank you for clarifying that.

What about withdrawing rewards? Is Uphold still the only option? And is it safe?

Gemini is coming up, creators already can use it (this gets NY state service) and users to follow. Also bitFlyer for Japan.

What about European users? Will there be any trouble withdrawing funds? I'm for Portugal, if that helps somehow.

Uphold already covers Portugal.

Thanks!
