I am using brave as a default browser on my Pixel and the ad free experience of web is amazing. I tried using firefox but that breaks up on so many websites and is slow so often it's not worth it. For me brave = chrome + ad-blocker on Android.
I have a bad taste in my mouth around crypto as well, but I don't think lumping all crypto efforts together is fair. What Brave tried to do was awesome IMHO. They wanted to promote an ad-free internet by making micro-transaction/micro-payment possible, which pays content creators. Particularly at the time they started it, crypto looked like a fantastic way to do that. That many scummy people starting creating shitcoins and pumping them to steal money from others really tainted the whole thing, but I strongly believe that was never Brave's intention.
