Why would you just send it like that? You do know that the amount you are transferring is quite big and in that case you should have checked the wallet before depositing any amount to it. They didn't send the notification but it was clearly written in the wallet list.
You can only HOPE that the Bittrex team is kind enough to credit the amount to your wallet after the suspension of wallet.
You can raise a ticket now that you have made a mistake to deposit the amount to your wallet while it was under suspension.
