I wouldn't say these are no-KYC exchanges, because some of them have checkboxes on their sign up pages reading "I am not a Politically Exposed Person", "I am not a US Person", etc. which seems to strongly imply an ID check is going to be waiting for you immediately afterwards.
Exactly, that's what I'm always speaking about. And that's why I like no KYC exchanges to be structured like Crypton exchange. Not a single piece of personal information is needed. They just need to list more coins to attract more users.
