Personally, I can see Brave being very popular with millennials and Gen Z, particularly with gamers as the browser could potentially be used as a way to pay for gaming memberships with BAT. I'm also looking forward to their ad platform which is due to be released and other applications in the works.
Brave browser mainly used by lot of users due to its privacy but in recent days people found that brave isn't completely providing privacy to its users so people moved to Tor from Brave and that is why brave itself showing that they have lot of active users so people can consider them for using it.BAT could be a reason why people using it but I am also using it for general surfing not for any privacy related things.I just go with Tor whenever I wanted to get complete privacy.
