At least in Brazil, the fake IDs are already a common market here. You paid just a few bucks to have them. Driver's licenses, personal IDs, credits card. You choose the person and they make very realistic fake documents. So now with the AI's ascension its not surprising that the face swap wil happem in this market.
Technology is getting more sophisticated, everything can now be done with AI, and selling KYC to an exchange for $15 and it passes, of course this will be a task that must be done by the Exchange so that no Fake AI profiles can get through. $15 for KYC is very cheap and this will be targeted by people who don't want to do KYC. There must be more valid scanning of identity on the exchange, if it is a fake identity then there will be account freezing and that will definitely happen. Exchanges also need to evolve and must leverage AI as well to check the identity of each user.
