Right now more normal potential. But the potential can skyrocket (literally) if Elon Musk gets involved in the project. But I do agree with you that it would be awesome if they had some feature that made it truly stand out from the competition! Since there are lots of browser option people have these days. Especially on Android the selection you have between great browsing experience is insane!
I suppose that iOS is a bit more dry when it comes to browsing experience options since Apple likes too much control. Apple lost most of it's hardcore geeks when jailbreaking became harder. So Brave browser over there will probably struggle a bit with it's potential. Apple even want to control you so much that they removed the headphone jack so you have to buy an overpriced adapter!
Main potential right now seems to be for advertisers to get in on the Basic Attention Tokens. They got the logo down real sharp I could see on coinmarketcap! A bit illuminati feels. Still a bit down from it's all time high around a month ago. For the regular consumer I don't really see the major selling point. Since block ads has been around for years now.
And reward other websites with Tokens will probably take at least a couple of years before it really starts to take off in a nice way. So right now it seems like we are mainly going to play the waiting game. Super curious when the Google guys will be starting to talk more about Crypto and Tokens. Then we finally can see if the big bad wolf got what it takes to compete with these new geeks on the block!
