I just downloaded and installed the browser, and I actually using it right now. This browser has a nice design, and it's pretty fast to load a page but also still a little bit buggy. And I don't really understand about the "earn Bitcoin with this browser" thing, they called it Ad Replacement btw.
So do you not actually get money from viewing their ads or does it just replace them with other different ads. I'm missing the point i guess
"Soon, micropayments and better ads will give users and publishers a better deal." - judging by this i don't think payments are implemented, but
it does claim to replace the ads with their own, so there's no "more" ads, just different ones.
