Interesting. It would be nice if Steem integrated an easier payment feature like this. I’ve dabbled with AMP and BAT but still feel like Steem has the edge. Voting is so frictionless compared to deducting from your own token balance.
Of course smart sites could actually use all three! A video site built on Steem with its own SMT could enable AMP and be a registered content producer with BAT & the Brave browser!
