I think that’s just with Brave browser, not Brave Search. At least, I can’t find anything related to crypto in Brave Search settings that are there in Brave Browser (I’m using Firefox with Brave Search).

EDIT: With Brave Search (not using the browser), I’m more concerned that the results are still being curated and some results censored. Whereas using something like Kagi, I can see the results are exactly what I would expect to be served, uncensored and uncurated (i.e. how Google and all the rest used to be before they decided they knew better than us what we wanted to search for.)
