As long as Monero or Bitcoin aren't accepted in my local grocery Store or online Shops, digital payments are the greatest issue in concerns of privacy for my privacy model.

Not sure if it can be done due to registrations, but having something disguise what the payment is and just show as a proton charge.
I know there have been many banks and visa amount others trying to have special charge codes and deny charges connected to firearms specifically. That will eventually branch to whatever they say is "bad".

I'd love to see the function added to Proton Pass, and make the debit and creditcards there function to pay in stores.
