I don't see many users getting the emails asking for the source of funds though so I guess my account is fine. I don't see any reason to panic if they ask for the source but I'd like to know if a lot of us received the email and goes on without worries after submitting documents. I checked my email which I find nothing is sent to me about it.
I have not logged to my account for a year but I have few tokens I kept like ADA but nothing much.
