I logged-in to Brave today to claim the free BAT. My balance is now 17.5 BAT. About 1-2 weeks ago, my wallet contained 50 or 60 BAT.
Things that I have recently done:
- Today I claimed the free BAT.
- A few days ago I updated my browser to the latest version. I never backed-up my wallet, but I also was never prompted to do so.
