Please get your facts straight.

1. Withdrawals work fine 95% of the time. This is not a Bittrex problem, but a problem with the STEEM wallet. It's also a problem with a number of other coins including bitcoin itself.
2. Withdrawals have been enabled the entire time we've had listed except when the devs asked us to pause during the security incident.
3. This is cutting edge technology, and there will be delays. Our support is committed to a 24 hour SLA. If we don't meet our SLA, please let us know.

As Hive account@ned has pointed out on all of your threads, this situation is present for anyone running the STEEM wallet.
