Brave recently released their MAU statistics which has reached a rather impressive 16.7M: https://mobile.twitter.com/BrendanEich/status/1290312177182621696?s=19

It's a subject of debate, but Brave which uses BAT as it's token, is somewhat of a 'sleeping giant'. 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.
