I'm not quite familiar with that Brave browser, nor is it legitimate and does actually pay off (which I assume is a yes since that payout amount is small), but it's also one great way for people to know about cryptocurrencies. It does help crypto in gaining more publicity and trigger their curiosity to learn more and potentially invest. However, I just hope it's not another scam because it would certainly affect crypto's image to the public. I have also not heard of BAT altcoin, but nevertheless, quite impressive for a browser to have a touch of cryptocurrency.
