I don't really see why people would massively start to use their Brave browser to browse the internet? The browser space is pretty much said and you need to have a pretty super browser if you want to change anything in that space I reckon. I for one will definitely not start using the Brave browser in order to see add's while in general I do not want adds during browsing at all. A huge percentage of people using Chrome have these add-ons that block all adds... If Brave will not be used by a massive amount of people, revenue from add watching will be not even worth it?
