I am a regular Cpdax exchange user til I logged in one day and realized my account has been suspended. When I sent Support a mail, they said they were discontinuing services to my country. They said I should apply for my account to be reactivated and withdraw my funds. Now the problem is they insisted I have to do KYC and with ONLY a passport. I told them I have only a driver's license which I have been utilizing in all my exchanges. They haven't been replying my mail til today.
I am very sad for your loss, but when you signed up on the exchange you agree to their terms and conditions, somewhere must say that you must provide identification for verification purposes, other scam exchanges like Cryptobridge
https://bitcointalk.org/index.php?topic=5189304.msg53016834#msg53016834 also use the same scam tactics, they refuse your KYC if you supply a drivers licence, even if the document is from a first world country like Canada, so if you are from a third world country, like North Korea, Syria or another country with international sanctions is very probable that you will need to get a passport to verify your account.
Keep updating this post and if there is enough evidence that Cpdax is a scam i will add it to my signature scam list
