Flattr tried it a while back where you could set aside 5 euro per month, or whatever, and they would distribute it to the stuff you liked the most. But the transaction fees were high for them and it was hard to do super small payouts.
This is a crypto case that makes sense. I’m not quite sure how they will keep an exchange rate with the dollar as the only thing you can buy with it is cash to content. So you can buy BAT from Brave.
