I've been using Revolut and their disposable cards for over two years now, but I never liked it as much as Privacy.com since they didn't allow you to set a spending limit.
And well, if it wasn't for your comment I would have never discovered that Revolut actually implemented said feature. Thank you!
It’s not perfect but it’s better than the alternatives. Last four of CC are often used for identity verification, but if I use a unique card number for every site, losing or leaking my Visa card won’t be as harmful.
