unfortunately you and hundreds of people who are in the same situation as your situation can only hire some lawyer and report the case to police because bittrex does not respond tickets sent to the support and this situation has got worse every day, there are people with hundreds of dollars blocked on bittrex and has hundreds of people who are complaining that their accounts have been disabled and added the fact that bittrex has registered many new users in the past months. so you can already see that the only way to have your problem solved is hire some lawyer and report the case to the police
