Not really, it all depends on your threat model and how high it's set.
How?
You will ask me to use duckduckgo.com for my search engine?
Well, yeah, that would be a good start, but if you don't like DDG, I'd recommend using SearX as a search engine (using a private instance/self-hosted) in the Tor Browser running on QubeOS.
About Brave, as long as they don't track me, sell my data or some shady stuff like this, I don't care about what KYC they implement *for publishers only*; If they need to do that in the eyes of the law/government, they will obviously do.
They won't sell the data to a third party or anything like that because, as it says in the link I posted above in this topic, they don't store the data that you provide, Uphold does since they're the ones who require and will receive the KYC info.
