Why would you even sell your own identity, that will be like a bs move from you. You are literally selling your own data to a stranger which can use it into something that might get you into a fall/danger.. I dont think there will be buyers too unless there are some people who wanna use other's identity to scam other people, they can literally use other exchanges as well if they wanna use an exchange which doesnt really require KYC (Know Your Customer)
