It does both. I think their bat token is a bad idea though. People aren't incentivised to do it.
It does filter ads, even if you don't pay, but they don't see that as a sustainable solution. I agree BAT isn't cutting it, but BTC fees weren't compatible :)
Agree. Though I think Moneybutton would be better if it could display a QR code as a fallback. It's burdensome to have an extra seed to store just to use MoneyButton.
