I'm actually tempted to start using Brave. I'm still holding out with Firefox despite Mozilla trying very hard to get rid of us (to the point where the thought has struck me more than once if the current CEO of Mozilla is in the pocket of Google). If at some point the last competing mainstream browser engine is gone I'll probably go for Brave and I might start testing it this week.
Brave is just Chromium with a cryptocurrency scam bolted on to it. I'm unhappy with Firefox's ad-related changes recently, but Brave is definitely not an option. If it came to it, I'd use a WebKit browser — objectively worse, but not clearly compromised.
The coin itself is one of the few that has a value based on some actual use, at that:
Brave sells adspace, gets paid in Money™. They keep a cut, take the rest and buy BAT with it, give it to users. Users can then tip content creators with the BAT and get some compensation for Brave's part in killing tracking ads.
Many people are idiots who do think that BAT is for them to get rich but like hell it is. Single ad viewers aren't very valuable, they only matter in aggregate, so you'll only ever get pocket money as BAT.
