Browser: Shows sponsored images along with pretty wallpapers on the new tab page (opt-out, one toggle to turn off, can turn off ads and leave Brave-sourced pretty images in). Users can opt in to Brave Rewards which shows them ads as toaster popups (how many is the user's choice), and users get a cut of the ad revenue as BAT.

Brave Rewards tipping service: Show users the toaster popups. Brave takes a cut when users tip creators or websites with the built-in tipping system.

Brave News: Funded by users having Brave Rewards ads enabled.

Brave Talk: Traditional subscription service.

Brave Search: Keyword-based ads, a traditional subscription for ad-free search.

Yes, it was launched at the beginning of April (I signed up). Also, they offer a subscription plan for $3 per month.

Yeah, but you opt in, and you receive a share of it (in their altcoin) if you do.

Different thing. That's their Brave Rewards thing, which shows you ads (your choice how often) as toaster popups and gets you a part of the revenue as BAT (which can be used to support creators with Brave's tipping service).

The search engine itself shows keyword based ads on search results pages, and Brave offers a $3/mo subscription for ad-free search.

they lost me at "altcoin"

Replace "altcoin" with "foreign currency" and it would be the same thing. You receive a payment, convert it to your local currency, and use it.
