It has been 7 days since I contacted Bittrex support about my disabled account.
So far they haven't even acknowledged the outstanding ticket.

Their system automatically replied a second after I opened the ticket stating "For Accounts valued at over $1000 USD we require additional information for proof of identity".
I submitted the required selfie and not even a peep from them.

It seems they feel they can appropriate your money without even owning an explanation. They are quite the professionals.
