Not the parent, but I can give some uses of my own. * All kinds of recurring payments. I pay for email, Dropbox, Patreon, and my VPS with cards that have monthly or yearly spending limits. * One time payments everywhere I don't have an account and don't want an account. I had to pay dues for a university club recently and I went through a super sketchy university website and payed with a burner card. 3 months later I get a "rejected transaction" email from Privacy telling me that someone tried to use my card at a Walmart. This isn't a common occurrence for me but it was nice to not have to cancel my real credit card.
