I’m confident that a number of us here are users of ProtonMail given the concerns for security and privacy that it shares with Brave. In fact, Proton Technologies recently became a verified Brave publisher. Anyway, I wanted to briefly share that there is an open feature request on the ProtonMail site to allow users to pay for the premium features of ProtonMail via BAT. I for one would love to see that. Please add your vote if you feel likewise!
