I guess if this BAT token will get popular, it might change the system a lot, for sure it wouldn't be good for steemit right now, because it still is not that popular as other platforms like facebook and instagram, but steemit is decentralized to some degree, this feature can keep it in game
When it's ads release this month, then using it on Twitter and Facebook, will replace regular ads with Brave ads (that pay), for twitter alone you could make a lot... that platform is filled with ads.
