Last first: in W-7 installations, I use multiple browsers (e.g.: IE and Chrome rarely; Brave, Firefox, Opera, and Vivaldi more frequently), each, for different on-line activity, reserving one browser (my choice is Vivaldi) for on-line banking and related financial transactions.
I heard about Brave and first installed an early version in late 2016 / early 2017 because of privacy and ad-blocking.
Barriers to Brave being my primary browser: First, lack of user control over updating. For me, that’s a non-negotiable Fail. It isn’t even open to discussion. I continue to use Brave, but only for non-essential activity. Second, while the concept of micro-payments to fund website publishers in lieu of advertising is appealing, use of cryptocurrency is also a non-negotiable Fail. Cryptocurrency as an option? Sure! But conventional modes of payment (e.g.: credit cards, electronic funds transfers) must be available.
