I used bittrex.com a long time ago (many years actually) and I have there a bit more then 0.5btc sitting in the account.
back then it wasn't THAT much, but now it became a lot more.
For some reason they do not tell, they decided to block the access from my account (I haven't used it for few years) and want me to send them tons of private documents! all this without explaining why, and while I have access to my email + password with 2fa AND a verified account.
Of course I can give them all the stuff they requested as i'm the legit owner, but i'm not interested in doing so as it is very private.
any suggestions?
