I think it is time to take legal action.
Okay, guys it is up to each of you to take screenshots of the balances listed at Bittrex, record the ticket number and make sure you have backups of your wallets you used to fund the exchange. Later you may need the transaction ids from the wallets.
Bittrex, always uses the same memo on Steem when accepting Spend-to-name cryptocurrencies from a given user. It is probable it always uses the same bitcoin and altcoin addresses when accepting from a given user.
If you are interested, please answer with "count me in" and your ticket number but take those screenshots and the transfer lists (transaction ids) of your wallet where you send to Bittrex.
