Teh one thing that is becoming increasingly prominent is the need for cryptocurrency exchange sites to require some sort of verification and KYC procedure and this generally involves you taking a picture of yourself and uploading your personal id document to the website as well. A turkish exchange BtcTurk, has admitted that in mid 2018 there was a leak in over 500000 users, where their id, details and mobile numbers were leaked and were sold on forums. What are your thoughts on this?
