I have a few websites and receive payments from Brave Rewards almost every month. They pay me in BAT, but since I don't care about BAT or can use it directly, it gets converted to my local currency, which I then can use to pay for stuff.

It's a mistake to assume something is nonsense or bad just because crypto is involved. Provided that you can convert it to something usable, it doesn't really matter if you're paid in dollars, BAT or something else.
