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?

Kiwi and Yandex browser leta you use any Chromium extension, and Firefox Nightly, with some hacks, lets you use any Firefox addon on the webstore. FireFox stable version also comes with uBlock though.
