Are there any brave users out there? no pun.
I use ff with DDG on PC and safari with DDG on ios. Never understood the reason for a move.
The ad rewards was just too much information for me, from brave.
I've recently moved to Brave because of their addition of IPS (which I see as an interesting technology). I've been really happy with Brave - especially on Mobile which feel way snappier.
Also not having to install a 3rd pary ad blocker (uBlock Origin) makes me feel more comfortable. Firefox should ship with a good ad blocker - it does not.
I've not played around with BAT yet - it's on my TODO list.
Brave seems to be pushing the boundaries more than other browsers, and it'll be interesting to watch where things go.
