They are set to start accepting BAT on Brave in the next couple of months. Only a year or so ago they were operating on the Bitcoin blockchain, now they're on Ethereum. The speed at which they get things done is pretty impressive imo.

Their main problem is their poor hype / marketing. That's an advantage in terms of buying BAT cheap at the moment but it's fustrating if you already have a load of BAT and you're watching the price keep ticking on downwards (me).... It won't do that for too much longer though :)
