The advertising industry will never take that as an option anyway. They're addicted to big data now. They have to sell a hell of a lot of less-annoying non-data-mined BAT ads to compensate, or do with less profit. They're not going to be on board.
And these tokens don't really solve the issue. People hate ads. Trading their ads for slightly less annoying ones when they can do without them altogether is not going to work. How many of those 65M brave users actually opt in to the BAT ads?
It's just a non-starter and will always be that. Sorry. It's just another fairytale spun to dig into VC money pools.
