Brave recently became my default browser, but I personally don't care for the crypto stuff.
The current iOS beta allows users to sync their bookmarks with Windows and iOS privately, and it's what convinced me to switch. I didn't need to create an account with my email address, or install iCloud...just scan a QR code.
I wish they'd fix the captcha problem though, a lot of sites that use ReCaptcha think Brave browser users are bots (due to the security).
