I write about the Brave browser and ecosystem repeatedly because I support the goals of the company – protecting individual privacy AND compensating online content creators. The success of this company depends on public adoption of the chromium browser, content providers signing up with Brave to receive compensation for viewer visits, and the support of the system by advertisers. I suppose contributions of participants to purchase BAT (the crypto used to compensate viewers and content creators) could be added, but this contribution seems less important that the other variables as the process could work without this component if enough people used the system, accepted the Brave collection of ads, and then used the BAT accumulated from ad exposure to compensate creators.
This recent article from Seeking Alpha summarizes data on these issues.
