Been using brave for a few years on mobile and desktop.

They uses to give away BAT, but they have refined their system to not give any unless you spend hours jumping through hoops and linking shoddy Chinese financial apps and crypto wallets.

I still use it for the privacy, but after reading this I will likely switch back to firefox or another chrome based browser.

Are there are any mobile browsers that have ad blocking like brave?

Firefox for Android lets you install ublock origin as an extension. I absolutely refuse to use any other mobile browser.
